| Abstract: | In order to study the influence of the structure of core sheet,the ratio of the diffusion bonding area between the core layer and cover layer,and the ratio of diffusion bonding area between core sheets on the strength of multi-layer structure fabricated by superplastic forming/diffusion bonding process,FEM is used to analyze the rigidity and strength of different parts with different structures of core sheet and process parameters.In the research emphasis is put on two critical factors: 0.5 H/L and the elon... |
