Abstract
A correction of the classical time discontinuous Galerkin (TDG) formulation that allows to achieve unconditional stability also in non-linear elastodynamics, i.e. renders the method truly energy-decaying, is proposed. Some numerical experiments are presented to illustrate the arguments discussed in the paper.File in questo prodotto:
