Abstract

Applying performance evaluation and optimization assisted by CAE to the structural design of car bodies and etc is becoming a universal procedure. In this study, an elasto-plastic material model appropriate for describing the work hardening properties of a metal material led by iron and steel was introduced into the topology optimization algorithm. And, optimization in crashworthiness of thin-walled steel structures was exemplified in numerical calculation. In addition, potentiality was revealed for application to the optimization of material arrangement potentiality as well as the topology optimization of structures.
