Abstract
Topology optimization for energy absorption is studied in this paper. Unlike conventional mean compliance formulation, this paper considers two main functions of vehicle structure: stiffness and energy absorption. During its normal usages, stiffness is chosen as the design objective. During impact, portion of vehicle structures absorbs impact energy while other part maintains the structural integrity. Therefore, we implemented a regional strain energy formulation to topology optimization. Sensitivity for regional strain energy is derived from the adjoint method. Numerical results from the proposed formulation are presented.
