Shape Function Optimization for Static Analysis of Composite Materials Used in Automotive Industry

Abstract

This study investigates the details of the static analysis of composite materials, which are increasingly important in the automotive industry due to their exceptional mechanical properties. The main focus is on the comparative analysis between already existing and newly developed shape functions, which aim to accurately describe the deformation behavior of composite structures. Special attention is paid to higher order shear deformation theories that use shape functions for more detailed modeling of the behavior of composite laminate plate. Numerical simulations are carried out using Matlab programming codes to precisely quantify the material responses under different loading conditions. The validation of the results is done through a rigorous comparison with the findings of relevant research. In particular, symmetrical cross-ply and angle-ply laminates are investigated to elucidate their specific mechanical properties and practical applicability in industrial settings. These results are crucial for the development of optimized structural solutions in the automotive industry, providing theoretical insights and experimental confirmation of the performance of composite materials in real operating scenarios.
