الوصف: | International audience ; When using FEM to solve wave propagation problems, the introduction of moving loads generates propagating parasitic waves due to the truncation of the computational domain. These waves can be avoided by introducing initial conditions obtained from a preliminary simulation. This techniqueis applied in the context of rail transport. A static load moving in sub-Rayleigh regime on an invariant by translation medium generates evanescent waves and is not taken into account in the prediction of ground vibrations in the far field. However, when the medium is heterogeneous propagating waves are generated |
