摘要：
An improved and accurate formulation of time-domain BEM for determining the interior stresses in a 2-D transient dynamic analysis is presented. A new set of simpler and better behaved transient dynamic stress-kernels is derived. With these interior stress-kernels, it has been possible to overcome all the analytical complexities that have hindered the accurate determination of interior stresses in the past. The accuracy and stability are established via a few numerical examples, including those involving stress concentrations. © 1990.
