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.

作为一种新型的轻质板材，研制了一种多孔金属层板。金属薄板层压板由三层组成，即两个薄的表层和一个带圆孔的穿孔芯层，它们通过扩散粘合结合在一起。通过研究平面应力条件下的屈服轨迹（等塑性工作面）和层合板的成形极限图，阐明了层合板的塑性变形行为和冲压成形性能。研究结果有助于掌握轻质多孔金属板层合板的结构与其变形行为和成形性能之间的关系，为层合板的设计提供参考。
