ELASTIC HALF-SPACE UNDER IMPULSIVE, DISTRIBUTED, VERTICAL LOADING AT THE SURFACE - EXACT SOLUTION AT THE CENTER FOR A PUNCH-LIKE DISTRIBUTION

The exact analytical solution for the vertical displacement at the cen ter of the surface of an elastic half space under an impulsive loading having the same spatial distribution as the contact stresses arising underneath a smooth, rigid disk when subjected to a static, vertical l oad, is obtained using Eason's method. The solution can be used to stu dy the dynamical interaction and contact problems between soil and str uctures and can also be used to assess numerical computations with a f inite element or boundary element program.
