000004679 520__ $$2eng$$aAn absorbing boundary condition based on the discontinuous Galerkin method is applied to transient analysis of elastic wave propagation in unbounded layered media. The boundary condition is exact in the finite-element sense, and the associated computational cost is an order of magnitude lower than for conditions based on Green functions. Furthermore, an implicit time-stepping scheme in conjunction with this boundary condition appears to lead to an unconditionally stable transient analysis procedure. Problems of foundation dynamics involving horizontally layered media are considered to demonstrate the performance of the condition.
