NiTi 记忆合金回复应力的计算机仿真

Computer Simulation for Recovery Stress of NiTi Shape Memory Alloy

介绍从ＮｉＴｉ形状记忆合金伪弹应力、回复应力与相变特征参量的内在联系出发，在实验的基础上利用计算机仿真技术建立回复应力与伪弹应力及温度、预应变之间关系的方法。

Based on the internal relations of pseudoelastic stress, recovery stress and martensitic transformation characteristic parameters of NiTi shape memory alloy, this paper describes the method for establishing the relationships between recovery stress and pseudoelastic stress, temperature and prestrain by the use of computer simulation technology.
