摘      要：A static and dynamic collaborative optimization method for materials and structure with uniform periodic microstructure is *** sensitivity formulae of hierarchical optimization,i.e.,material design,structure design and integrated design for porous metals,are *** the base of the hierarchical optimization model,numerical experiments of an MBB beam and a cantilever one were carried *** on porous metals bearing multi-functionality,the differences and applicability of hierarchical optimization are discussed in the structure loading *** is concluded that structure design is mainly oriented to structure efficiency,material design is mainly oriented to multi-functionality,and integrated design is oriented to structure efficiency and *** work provides some useful ideas for the selection of porous metals design method.

主 题 词：porous metals multi-objectives hierarchical optimization material design structure design integrated design of materials and structure
