| 摘 要： | 采用形状记忆合金（ＳＭＡ）的本构方程和有限变形理论，考虑拉、压不同应力状态对相变点移动的规律，编制了ＳＭＡ轴对称大变形有限元程序．通过实例计算，与单向拉伸下解析所得的应力、应变曲线基本吻合，证明了程序的正确性．

| Abstract: | The constitutive equations of the shape memory alloys (SMA) and the finite deformation theory are adopted. Considering the variety of phase transformation temperature due to the different stress states of tension and compact, the finite element program (FEP) for axisymmetric large deformation is developed. Comparing with the stress strain curve of the analytical result of the one dimensional case, the FEP is proved to be valid. |
