Among the open design issues for structural laminated glass (LG) elements, their mechanical performance during fire exposure stands as a safety concern. This issue is the focus of this paper. An experimental investigation is conducted to evaluate the effect of non-uniform thermal gradients on the out-of-plane bending capacity of standard LG specimens. The pre-fracture, cracking, and post-fracture performances of LG panels were examined using a three-point bending setup. The bending tests were carried out on un-heated LG samples and heated samples, which were either hot or cooled down. The reliability of available analytical and numerical methods to predict the out-of-plane bending performance of LG is then investigated. The accuracy of the analytical and numerical methods was found to be highly affected by the non-uniform thermal boundaries, as well as by the assigned material properties, which are highly sensitive to the fire exposure.

The present work reports an efficient way of capturing real-time crack propagation in concrete structures. The modified spectral analysis based algorithm and finite element modeling (FEM) were utilised for crack detection and quantitative analysis of crack propagation. Crack propagation was captured in cement-based composite (CBC) containing saw dust and M20 grade concrete under compressive loading using a simple and inexpensive 8-megapixel mobile phone camera. The randomly selected images showing crack initiation and propagation in CBCs demonstrated the crack capturing capability of developed algorithm. A measure of oriented energy was provided at crack edges to develop a similarity spatial relationship among the pairwise pixels. FE modelling was used for distress anticipation, by analysing stresses during the compressive test in constituents of CBCs. FE modeling jointly with the developed algorithm, can provide real-time inputs from the crack-prone areas and useful in early crack detection of concrete structures for preventive support and management.

The COVID-19 reported by China in December 2019 has claimed more than 0.79 million lives by August 20, 2020. The development of SARS-CoV-2 has been specified as the third most pathogenic coronavirus for the human community in the twenty-first century after the earlier reported coronaviruses such as MERS-CoV and SARS-CoV. However, the exact case fatality rate determination for SARS-CoV-2 suffers with limitations in accuracy and limited availability of data. The objective of the present work includes providing an interim insight into virology, origin of SARS-CoV-2, epidemiology of COVID-19, diagnostics and treatment based on the literature. A detailed summary of articles reported on virology of SARS-CoV-2 is reported in the chapter. This chapter also reports developments in vaccines and therapeutics to cure COVID-19 briefly. The differences between the demography and contact structure of India, USA and Spain were studied. A mathematical model was constituted for predicting COVID-19 spread in India. This chapter should provide a quick understanding of the present status of literature on COVID-19.

Microwave absorbing (MA) materials are frequently used in military and civilian applications. The researchers are focusing on the development of high performance but lightweight MA materials. Carbon fiber (CF) based MA materials are lightweight and offer a wide range of microwave absorption properties that can be fine-tuned for a particular application. A review of the endeavors toward the development of CF-based MA materials is presented here. Four types of CF-based materials for MA applications are considered, namely: CF reinforced composites, CFs deposited/coated with other materials, CF-based hybrid systems, and hollow and PCF-based microwave absorbers. Parameters affecting MA properties of CFs and derived materials have been assessed. It has been emphasized in the literature that the optimum characteristics of CF-based materials can be obtained by manipulating geometry, morphology, concentration, and treatment. Although the MA capability of CF alone is poor, in tandem with suitable materials or with special geometric features, they may serve as important MA materials. Interfacial polarization, uneven electron distribution, reflection loss (RL) and multiple reflections have significant roles in enhancing the microwave absorption of these materials.

The constraint groove pressing (CGP) is a severe plastic deformation (SPD) method for producing ultra-fine grained sheet metals. Firstly, the present study reports the effect of CGP on mico-hardness, tensile strength, and grain size in the multi-pass CGP of aluminium and copper. The aluminium and copper sheets are processed up to two passes. The improvement in tensile strength and hardness after every pass due to grain size reduction is reported. Further, an empirical model that correlates residual stresses and grain size is established. The residual stresses were measured by X-ray diffraction (XRD) and layer removal technique along the thickness of the samples. Moreover, the effect of residual stress nature on mechanical properties is investigated. It is found that the micro-hardness of the sheet depends on the nature of residual stress. Finally, a finite element (FE) model is constituted to predict the stresses, deformation, and residual stresses after every pass. This FE model can be used for exploring possibilities of improving the process capability of CGP by examining conditions not evaluated during experiments. The residual stress, Von Mises stress, deformation were decreased with the decrease in grain size up to two passes.

The present work aimed to develop an efficient way of capturing real-time crack propagation in concrete structures. The image processing was utilized for crack detection, while finite element modeling (FEM) and scanning electron microscopy (SEM) were used for quantitative and qualitative analysis of crack propagation. A green cement-based composite (CBC) containing saw dust was compared to a reference M20 grade concrete under compressive loading. Crack propagation during compression tests was captured using an 8-megapixel mobile phone camera. The randomly selected images showing crack initiation and propagation in CBCs were used to assess the crack capturing capability of a spectral analysis based algorithm. A measure of oriented energy was provided at crack edges to develop a similarity spatial relationship among the pairwise pixels. FE modelling was used for distress anticipation, by analyzing stresses during the compressive test in constituents of CBCs. SEM analyses were also done to evaluate cracked samples. It was found that FE modeling could predict the crack prone regions that can be used jointly with the image analysis algorithm, providing real-time inputs from the crack-prone areas. Green CBC were compared to reference concrete samples, showing reliable results. The replacement of OPC with wood dust reduced compression strength and produced a different fracture pattern regarding reference concrete. The results of the study can be used for distress anticipation and early crack detection of concrete structures for preventive support and management.

Fire is a significant threat to human life and civil infrastructures. Builders and architects are hankering for safer and sustainable alternatives of concrete that do not compromise with their design intent or fire safety requirements. The aim of the present work is to improve the residual compressive performance of concrete in post-fire exposure by incorporating by-products from urban residues. Based on sustainability and circular economy motivations, the attention is focused on rubber tire fly ash, aged brick powder, and plastic (PET) bottle residuals used as partial sand replacement. The selected by-products from urban residues are used for the preparation of Cement-Based Composites (CBCs) in two different proportions (10% and 15%). Thermal CBC behaviour is thus investigated under realistic fire scenarios (i.e., Direct Flame (DF) for 1 h), by following the International Organization for Standardization (ISO) 834 standard provisions, but necessarily resulting in nonuniform thermal exposure for the cubic specimens. The actual thermal exposure is further explored with a Finite Element (FE) model, giving evidence of thermal boundaries effects. The post-fire residual compressive strength of heated concrete and CBC samples is hence experimentally derived, and compared to unheated specimens in ambient conditions. From the experimental study, the enhanced post-fire performance of CBCs with PET bottle residual is generally found superior to other CBCs or concrete. The structure–property relation is also established, with the support of Scanning Electron Microscopy (SEM) micrographs. Based on existing empirical models of literature for the prediction of the compressive or residual compressive strength of standard concrete, newly developed empirical relations for both concrete and CBCs are assessed.

The waste sugarcane dry leaves were utilized as the reinforcement with the epoxy matrix to prepare the sugarcane dry leaves reinforced polymer composites (SDLRPCs). The tensile, compressive, impact and flexural tests were conducted following respective ASTM standards. The proportion of SDL in SDLRPCs for the most effective fiber–matrix interaction was determined. The statistical analysis has confirmed that the error in experimental results was within the specified limits. The resistance to natural weathering of SDLRPCs were evaluated following ASTM D5338-11. The effect of weathering on tensile strength was also investigated. The scanning electron microscopy (SEM) micrographs revealed reasons for fracture of SDLRPC samples during mechanical testing. It was noticed that the biodegradability corresponds with resistance to natural weathering; more biodegradable wood plastic composites were having the lesser resistance to natural weathering. The micromechanical finite element (FE) model coupled with the numerical homogenization technique (NHT) was constituted to predict the elastic properties of SDLRPCs. The micro-scale stress analysis revealed that the von Mises stress for SDLRPC was up to 267% higher than the pure epoxy. The transient/static micro-mechanical models were constituted to predict the tensile, compressive, impact, and flexural behavior of SDLRPCs. The developed models were found in-line with the experimental data.

Transparency, illumination, aesthetic and energy requirements have considerably increased the use of glass in modern high-rise buildings. During fire exposure, fracture and shattering of windows and facades accelerate the spread and severity of fire, which increases the risk for the occupants and the amount of structural damage. This paper aims at analyzing the effect of non-uniform thermal gradients on the flexural capacity of ordinary glass panels. Both transparent and tinted glass panels are considered to account for widely-used glass compositions. The bending response of fire-damaged glass panels is experimentally explored considering different durations of thermal exposure. The thermal breakage due to non-uniform temperature distributions over the height is also assessed. A finite element investigation is then conducted to further explore the experimental findings.

The present work reports the inclusion of different proportions of Mango/Sheesham/Mahogany/Babool dust to polypropylene for improving mechanical, wear behavior and biodegradability of wood-plastic composite (WPC). The wood dust (10%, 15%, 20% by weight) was mixed with polypropylene granules and WPCs were prepared using an injection molding technique. The mechanical, wear, and morphological characterizations of fabricated WPCs were carried out using standard ASTM methods, pin on disk apparatus, and scanning electron microscopy (SEM), respectively. Further, the biodegradability and resistance to natural weathering of WPCs were evaluated following ASTM D5338-11 and ASTM D1435-99, respectively. The WPCs consisting of Babool and Sheesham dust were having superior mechanical properties whereas the WPCs consisting of Mango and Mahogany were more wear resistant. It was found that increasing wood powder proportion results in higher Young’s modulus, lesser wear rate, and decreased stress at break. The WPCs made of Sheesham dust were least biodegradable. It was noticed that the biodegradability corresponds with resistance to natural weathering; more biodegradable WPCs were having the lesser resistance to natural weathering.

The use of natural fiber composites in the fatigue prone structures is limited due to the lower strength and durability when compared to the carbon fiber reinforced polymer composites. The present work focuses on improving the bending cyclic fatigue strength (CFS) of the sugarcane fiber reinforced epoxy composite (SFRPC) by a novel treatment method. The treatment has increased up to 40% fatigue life of SFRPC by fiber and interface strengthening. The fatigue life was evaluated using the standard bending cyclic fatigue test. The SFRPCs were prepared using a specially designed compression molding setup by the hand layup method. The sugar cane fibers (SCF) were treated using the waste glass powder and PVA adhesive. The statistical analysis was conducted to observe the effect of the treatment method, the load ration (R) on CFS of treated/untreated SFRPC. A comparison of CFS of SFRPC (treated/untreated) with CFRPC is presented based on the author's previous work. A finite element based model was constituted for predicting the elastic properties of SFRPC (treated/untreated) at different fiber proportions. Additionally, a finite element (FE) model was constituted using the transient analysis in ANSYS (Explicit Dynamics Module) for obtaining the deformation and Von Mises stress at different R for the corresponding life of the treated/untreated SFRPC sample. A theoretical explanation for improved fatigue behavior of SFRPC was presented using scanning electron microscopy (SEM) micrographs and FE results collectively. The stress-strain-life relations for treated/untreated SFRPC were established. It was found that the shear yielding resulted due to the fracture of the outer glass layer of the SCF resulted in the higher CFS of the treated SERPC.
