“…Authors considered the step change of properties along the height of the structures. Recently, the nonlinear static and dynamic response of thin-wall composite structures were investigated [23][24][25][26] by employing finite element method with firstorder shear deformation theory. Here, author considered a high-rise building as a cantilever plat to study the static and dynamic behavior of these thin-wall structures.…”

This chapter emphasizes on the static and dynamic characteristics of multi-story building subjected to uniformly distributed and wind load. First-order shear deformation theory is used to formulate governing equations based on the finite element method. The multi-story building is considered as a vertical cantilever beam/plate and modeled using nine-node degenerated shell element. Fictitious membrane and shear stresses are eliminated by considering Mixed Interpolation Tonsorial Component (MITC) technique. Here, the static and dynamic characteristics of multi-story buildings have been investigated take into account as a vertical cantilever plate subjected to UDL, triangular load (wind load) and combination of both. In this chapter authors demonstrated the deformation shapes, longitudinal stress and in-plane shear stress and principle strains in various loading conditions of vertical cantilever flat panel. Moreover, investigated the dynamic characteristics of multi-story buildings considering as a vertical cantilever plates and governing equations of motion are derived by employing Hamilton’s principle. Moreover, nonlinear transient response of high-rise structures has been studied here by employing the energy and momentum conservation implicit time integration scheme. The structural analysis of tall buildings has been carried out here through commercial software ANSYS. Matrix amplitude method is employed to investigate the large-amplitude flexural vibration responses of flat panels. Also, plotted the fast Fourier transform and phase portraits for first three bending modes.

“…When homogeneous heat stress is applied to curved (trapezoidal, cylindrical) panels composed of laminated composites, Kumari and Lal investigate the flexural characteristics of these panels. These panels are often seen in military vehicles, cars, ships, and aeroplanes 151,152 . The thermal characteristics of the eucalyptus fiber composite, which is based on polyester and has volume fractions of 30%, 40%, and 50%, indicate that the thermic stability drops significantly as the amount of fiber included in the composite increases, as compared to the pure polyester material.…”

High performance and durability are essential for goods to satisfy the needs of the expanding worldwide market. Wood plastic composites (WPCs) are materials made from a combination of wood, polymers, and additives. WPCs can be extruded, injected, compressed, or thermoformed. Presently, WPCs are manufactured using sophisticated processes including as laser sintering, fused layer modeling, and additive manufacturing. Properly managing the melt temperature and pressure is crucial in the manufacturing process of WPCs to ensure effective polymer incorporation. Natural fibers have distinct benefits for polymer composites, but they also have some serious drawbacks, like lower strength properties—especially lower impact strength than synthetic fibers—poor compatibility with hydrophobic polymers, poorer dimensional stability and moisture absorption due to hydroxly groups, a maximum processing temperature that is limited, thermal degradation above 200–220°C, and lower biological durability. The modification of the surface of the fibers improves the mentioned disadvantages of the natural fibers. High‐quality WPCs require the application of chemical or physical treatment to the wood fibers. This extensive review focused on the modification techniques applied to the surface of wood, manufacturing processes, and properties and applications of WPCs.Highlights Modification methods used in surface treatment of natural fibers was explained. Properties and recent applications of wood polymer composites were given. Optimum requirements of natural fibers and polymer matrices are given. Fabrication methods of natural fiber composites are extensively given.

“…Design and shape optimization of connecting rod was carried out by Vijayvergiya et al [5] and optimization of cylinder head was conducted by Kumari et al [6]. Recently, analysis of thin-wall structures was carried out [7][8][9][10] in the presence of thermal and mechanical load considering various boundary conditions. Clark [12] and Fanghui [15] studied the free-floating piston pin behavior of heavy-duty engines'; further static responses of piston pin has been investigated by Debnath and Debnath [12].…”

In this article, authors discussed the various boundary conditions (fully floating, semi floating and stationary) and failure modes (transverse crack and longitudinal crack) of piston pin of IC engine. Moreover, authors given the empirical relations for shear stress, bending stress and ovalization stress to design piston pin for internal combustion engines. Furthermore, carried out the force analysis on piston pin and expressed the empirical relations for force analysis of piston pin that will be very useful for design of piston pin for petrol and diesel engines.
