| 摘 要： | The material structure of laminated vibration damping steel sheet（LVDSS） was introduced in detail. An interface cohesive model between the skin sheets was developed by using a contact/interface approach, and the model was applied to simulate ＂T＂-peel and lap-shear processes of LVDSS. The interface contact stress distribution during the ＂T＂-peel and lap-shear processes is obtained, and the finite element analysis（FEA） results agree satisfactorily with the corresponding experimental results. As a result, the model is suitable to simulate the cohesive of LVDSS
