  The conventional time-domain boundary element method(TD-BEM)utilizing dynamic fundamental solutionsis particularly suitable to elastodynamics due to its unique features of boundary discretization as well as preserved causality conditions.Itscomputational costs however pose a serious challenge as the coefficient matrices need to be calculated and stored for each time step.An alternative way to derive the BEM for dynamicsis based on static fundamental solutions.One attractive feature of this method is that the coefficient matrices only need to be evaluated and stored once,although the associated domain integrations need to be properly treated.
