Application of Physical Principles in Vehicle Stresses and Deformations to Optimize Automotive Safety and Performance

Abstract

This work highlights the relevance of physics in automotive engineering, particularly in the analysis of stresses and strains during vehicle design. Its application is essential for improving the safety, efficiency, and durability of automobiles, as it enables a better understanding of how internal and external forces affect vehicle components. The study emphasizes the need to analyze the stresses and deformations caused by these forces, which is fundamental for properly selecting materials and structuring more resistant designs. Additionally, finite element analysis is mentioned as a key tool that facilitates the simulation of material behavior under various loading conditions. This technique allows engineers to predict the point of maximum deformation, yield strength, and breaking point of the materials used, thus optimizing the vehicle's safety systems. Finally, the importance of implementing controlled deformation zones is stressed—these areas are specifically designed to absorb impact energy in the event of collisions. By deforming in a predictable manner, they protect occupants and significantly enhance performance in terms of passive safety. Overall, the study demonstrates how applied physical knowledge contributes to the advancement of automotive technology.
