Finite Element Analysis and Crashworthiness Optimization of Foam-filled Double Circular under Oblique Loading

Abstract Finite element analysis and optimization design carry out for the quasi static responses of foam-filled double circular tube is presented in this paper. In the investigation of the crashworthiness capability, some aspects were considered for variations in geometry parameters of tubes and the loading condition to investigate the crashworthiness capability. Empty, foam-filled, and full foam-filled doublé tubes of thin walled structures were observed subjected to oblique impact (0˚ - 40˚). The numerical solution was used to determine the crashworthiness parameters. In addition, NSGA I...
