Abstract
This research investigates the crashworthiness of innovative crash box designs utilizing thermoplastic polyurethane (TPU) as a potential alternative to traditional materials. Two unique crash box geometries were developed and simulated using ABAQUS software. The study analyzed the impact performance of three different TPU grades (85A, 95A, and 64D) on energy absorption, peak crush force, and deformation behavior. The objective is to identify optimal material-design combinations for enhanced crashworthiness, contributing to advancements in vehicle safety and light weighting strategies.
