Abstract: In this paper, by using the method of tensor operation, the fundamental solutions,given in the references listed, for a concentrated force in a three-dimensional biphaseinfinite solid were expressed in the tensor form, which enables them to be directly appliedto the boundary integral equation and the boundary element method for solving elasticmechanics problems of the bimaterial space. The fundamental solutions for Mindlin’sproblem, Lorentz’s problem and homogeneous space problem ore involved in the presentresults.

Key words: three-dimensional bimaterial, fundamental solution of a concentratedforce, tensor expression
