Accurate 3-D finite element simulation of elastic wave propagation with the combination of explicit and implicit time-integration methods

► The extension of the two-stage time-integration approach for elastodynamics to the use of explicit time-integration methods. ► The calibration of the amount of numerical dissipation for filtering spurious oscillations for the lumped mass matrix. ► In contrast to existing finite element techniques, the suggested technique accurately solves wave propagation problems. ► Accurate finite element solutions of several 3-D wave propagation and impact problems.
