Assessing the Crashworthiness Analysis on Frontal and Corner Impacts of Vehicle on Street Poles Using FEA
Abstract
:1. Introduction
- Assessing the damage of both the street pole and the vehicle during impact. The geometry and material definition of the street poles are comprehensively defined in detail to provide the results and compare them to accidents alongside experimental and numerical data of this nature.
- Analyzing whether a frontal or corner collision will cause higher damage on the street pole, the car, and even possibly both through qualitative FEA results.
