The Analysis of the Interface States of Low-density Materials in the Forming Process

摘要：

　　The interface of two low-density materials is bent in the forming process,which decreases the performance of materials.The theoretical analysis of the interface state in the forming process was taken to solve this problem,and the results indicated that the viscosity of the low-density material was very important to the interface state.The finite element simulation was also used to investigate the factors that affect the interface state.The results revealed the viscosity of material and the pressure were the main factors that affected the interface state; the stress and displacement at the interface could be accurately predicted by the finite element models.The ultimate aim was to modify the relevant parameters in a way that could obtain the required interface states.
