Temporal-spatial dispersion errors in fem modelling of wave propagation and implicit time integration
Original language description
During the finite element modeling of wave propagation in solids, both the spatial and temporal discretization lead to dispersion errors. These nerrors introduce the dependency of the phase velocity of propagated wave on its frequency. For the implicite time integration scheme, particularlynthe Newmark method, an optimal time step size is derived.
