Static Design Based on Hierarchy Optimization Associating Materials and Structures
In order to study the comparison of material design, structure design and integrated design about the porous material, a concurrent topology optimization design model associating materials and structures with periodical microstructures is presented. The sensitivity formulae of hierarchy optimization are given based on the integrated design model and related numerical experiments were carried out. The applicability of hierarchy optimization is discussed and their advantage and disadvantage are analyzed through numerical examples which provide some useful opinions about the porous material design.
