摘要
为求解三维动态热弹性问题提出了一种基于特征线法的数值方法，并对矩形截面的热弹性棒在冲击载荷和热冲击同时作用下的三维应力波传播过程进行了数值模拟。
This paper is concerned with the numerical technique based on the method of characteristics for three-dimensional dynamic thermoelastic problems. A numerical example for the threedimensional stress wave propagation in a thermoelastic bar of square cross section subjected to both an impact loading and a thermal shock is presented.
