报告摘要:
A specialized model oriented to near-surface elastodynamics is established. It enables to split calculations into two stages. First, a wave problem is solved on the surface. Then, the interior field is determined from an appropriate static formulation. The model is adapted for a broad range of moving load problems inspired by modern high-speed railway transport. In particular, three-dimensional analysis of a coated half-space under a point force moving with a speed close to the Rayleigh wave speed is developed. Comparisons with several known solutions of plane strain steady state and transient problems demonstrate the advantages of the developed approach for modelling near-resonance regimes.
