The boundary integro-differential equations ofthree-dimensional Neumann problem in linear elasticity

Summary. In this paper, we mainly consider the three dimensional Neumann problem in linear elasticity, which is reduced to a system of integro-differential equations on the boundary based on a new representation of the derivatives of the double-layer potential. Furthermore a new boundary finite element method for this Neumann problem is presented. Received July 13, 1992 / Revised version received June 28, 1993
