摘要
建立了在复杂应力状态下的热力学本构关系 ,并针对纯剪状态下的具体问题建立了热力学非线性方程的求解方法 .利用MATLAB编写的数值计算程序 ,对形状记忆合金耗能弹簧进行了实例计算 .结果表明 ,所建立的方法适用于热力学方程的求解 。
The thermodynamic constitutive relation under complex stress state was developed. The extract method of the thermodynamic non linear equation was also presented. With the numerical method programmed by Matlab a numerical example of shape memory alloy spring was presented to illustrate the correctness of the approach. The results indicated that the method presented was rational.
