Crashworthiness of Electric Vehicles [PDF]
World Electric Vehicle Journal, 2010 This paper describes the crashworthiness of electric vehicles when the vehicle has alterations from a gasoline engine to an electric motor. The crashworthiness is dependent on the crushable length of the frame and the center of gravity. It is presumed that the transfer of the center of gravity has the disadvantage in a crash.

Adaptivity in Crashworthiness Calculations [PDF]
Shock and Vibration, 1993 h-Adaptive finite element methods for nonlinear transient analysis by explicit time integration are described. Examples are given of adaptive calculations for simple components and prototype calculations for a full car model. h-Adaptivity offers substantial reductions in data preparation costs and improvements in accuracy.

Adaptive Twisting Metamaterials
Advanced Materials, EarlyView.This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.
