摘　　要：In this paper, the fundamental solution of the bi-material elastic space is studied. Usingthe Papkovich-Neuber solution and the Kelvin state of the 3-dimensional elasticity, thedisplacement field of the bi-material elastic space where a concentrated body force is appliedin the interior, is obtained. As several special cases, the solutions of the Lorentz problemand Mindlin problem in the elastic half space, and the solution of the analogue problem inthe Stokes flow can all be deduced from our results.In this paper, the fundamental solution of the bi-material elastic space is studied.
