Crashworthiness Simulations using LS-DYNA

This repository contains my crashworthiness and occupant safety simulations performed during professional training at Eleno Inc. The work demonstrates explicit dynamic analysis of automotive structures with a focus on energy absorption, deformation modes, intrusion behavior, and regulatory compliance.
