非稳态温度场中孔附近的动热应力集中

摘要

研究了非稳态温度场中任意形腔体附近的热动应力分布.通过Laplace变换获得了用Hankle函数表示的解析解,再通过Laplace逆变换给出了圆腔及椭圆腔附近的DTSDC的数值计算结果.%The dynamic thermal stress distribution of an arbitrary - shaped cavity in an unsteady temperature field is investigated. An analytical solution, represented by Hankle functions, is obtained by Laplace transform technique. Some numerical results are given by the inverse Laplace transform in the neighborhood of a circular and an elliptic cavity.
