- Generally, most of the fractions are occurred because of a lack of resistivity knowledge in internal structure level at abnormal loading conditions such as shock load, impact load, aerodynamic load, etc. Aforesaid loads drastically affect the structural performance of a component. The detailed pre-defined study about aforesaid loading environments and their side effects can provide the details of withstanding capability at peak loading conditions. This work examined the behavior of composite materials, which are subjected to sudden loading conditions at different real-time applications. Automotive vehicles and their components such as four-wheeler bumper, main bike stand, and automotive passenger bus are predominantly imposed these comprehensive investigations. The three primary different composites such as CFRP [Carbon Fiber Reinforced Polymer], GFRP [Glass Fiber Reinforced Polymer], and KFRP [Kevlar Fiber Reinforced Polymer] are selected and implemented under crash analysis with the support of various structural methods based on FEA in ANSYS Workbench. The comparative analyses are examined based on the stumpy structural parameters for instance impact stress, equivalent stress, and equivalent strain. The various different grid convergence tests are conducted, which ensured the correctness of computational procedures and discretization. The conventional approaches are imposed at all the three picked real-time applications and thus achieved the error percentages within the acceptable limits, which guaranteed the production of reliable structural outcomes. The suitable composite material is finalized based on low defect affectability for all kinds of crash applications, which is KFRP composite. Furthermore, the FSI [fluid-structural investigations] are carried out on automotive buses under maximum speed conditions, and thereby the suitable material is finalized. Finally, under the crippling load, the main bike stand is analyzed for various lightweight materials. Thus, the lightweight material with respect to automotive vehicles and their components are listed and suggested for future implementations.
