Abstrakt: A novel explicit integration algorithm in the predictor-corrector form for finite element computations of discontinuous wave propagation problems in solids is presented. The nominated algorithm, with the component-wise partition of equations of motion to longitudinal and shear parts, is designed to more precisely integrate wave propagation in accordance with their dierent propagation wave speeds and their stability limits.
