Treatment of fast moving loads in elastodynamic problems with a space-time variational formulation

The treatment of fast moving loads is faced with a variational space-time approach. A time integration algorithm and the variational treatment of fast moving loads are developed. The time integration algorithm and the treatment of moving loads are based on Hermite’s polynomials with independent field of velocities and discontinuous time derivative of the displacement field. The algorithm exhibits 6th order convergence and computational efficiency to treat problems of fast moving loads.
