Response of a 3D elastic half-space to a distributed moving load Nihal Ege∗†, Onur ahin‡ and Bar ³ Erba³

Abstract

The dynamic eect of an out of plane distributed moving load on thesurface of an elastic half-space is considered. The problem is formulatedin terms of a hyperbolic-elliptic asymptotic model for a movingload where the trajectory and the distribution of the load are taken tobe orthogonal. Steady-state equations are written in terms of a movingcoordinate system. The near-resonant solutions are, then, obtained forsub and super-Rayleigh cases taking into account the causality principle.Numerical results of displacement components are presented forvarious values of the distribution parameter.
