摘　　要：为描述ＴｉＮｉ形状记忆合金马氏体式转换和Ｒ相转换引起的形状记忆效应和伪弹性，在综合考虑与上述两个变化相关的诱导相体积变化的基础上，推导了一个热力学本构方程。该方程能很好地表达形状记忆效应，伪弹性和回复应力。In order to describe the shape memory effect and pseudoelasticity due to the martensitic transformation and the R-phase transformation of TiNi shape memory alloy,a thermomechanical constitutive equation considering the volume fractions of induced phases associated with both transformations is developed.The proposed constitutive equation expresses well the properties of the shape memory effect, pseudoelasticity and recovery stress.
