| 摘 要： | 利用形状记忆因子,直观地描述了形状记忆合金(SMA)实现其超弹性与形状记忆效应的热力学宏观过程.根据热力学基本原理并假设SMA为各向同性材料,建立了描述复杂应力状态下SMA热力学行为的三维本构方程.该本构方程具有直观的表述形式且所含材料常数均可以通过宏观实验测定,克服了现存SMA三维本构方程由于表述形式复杂和材料参数不...

| Abstract: | The thermomechanical macro-processes of super elasticity and shape memory effect occurring in shape memory alloy(SMA) are directly described using the concept of shape memory factor.A three-dimensional constitutive equation is developed based on thermodynamics and the assumption that SMA is an isotropic material.It overcomes both limitations that the previous three-dimensional constitutive equations are not available to predict the mechanical behaviors of SMA in the complex stress state and fail to express ... |
