Abstract
AbstractA scheme of internal stress calculation is established in the time domain boundary element method (BEM) for wave propagation in anisotropic media. For an internal point, total stresses can be achieved by introducing the high‐precision formulas of numerical differentiation and using the displacement solutions around the internal point. This technique is tested and applied to two numerical examples. The results show that it is not only reliable but also accurate enough, and can be utilized in the stress analysis of dynamic problems, especially those of wave propagation in anisotropic media.
