| Research Abstract |
As a new lightweight sheet material, a kind of porous sheet metal laminate was developed. The sheet metal laminate consists of three layers, i.e. two thin skin sheets and a perforated core layer with round holes, which are bonded together by diffusion bonding. Plastic deformation behavior and press formability of the laminate were clarified by investigating yield locus (equi-plastic work surface) under plane stress condition and forming limit diagram of the laminate. Results of this research make it possible to grasp the relation between the structure of the lightweight porous sheet metal laminate and its deformation behavior and formability, and help the design of the laminate.
