THE EFFECT OF A MOVING LOAD ON A VISCOELASTIC HALF-SPACE

Abstract

Cole and Huth have studied the effect of a line load moving with constant velocity V along the surface of an elastic half-space. The present paper treats the equivalent problem for a viscoelastic (standard solid) material when the velocity V is less than the velocity cs of shear waves of high frequencies. No solution could be obtained when the velocity V was equal to the velocity of Rayleigh waves. The present analysis yields a solution for this special velocity. It also permits an evaluation of the effects of viscosity at other values of V. In certain ranges these effects are minor, but in other ranges major differences occur due to focusing phenomena.
