摘　　要：对铅的有限变形压缩试验进行了分析,给出了基于拉格朗日描述的有限压缩本构模型,对设计侧向约束的复杂应力状态进行了理论探讨.无量纲压力的理论模拟值同试验结果一致,表明基于拉格朗日描述的本构模型可应用于复杂应力状态情形.The finite compression deformation property of lead under single and complex strength state is analyzed. The finite compression constitutional equation based on Lagrangian configuration is presented. Complex strength states such as compressing metal with the side constraint is designed, then the theoretical study is processed. Numerical results are in good accordane with the experiment which shows that the constitutional equation based on Lagrangian configuration is suitable for demonstrating the finite compression deformation property in complex stress state.
