ON THE CORNER TENSOR IN 3-DIMENSIONAL LINEAR ELASTICITY

The subject of this paper is the corner tensor C that appears in the f ree term in a boundary integral equation formulation for three-dimensi onal linear elasticity. A general corner, locally composed of piecewis e flat and curved surfaces, is considered in explicit fashion. The sol id angle at the corner appears in the expression for C. A new formula for the solid angle at a general corner, in terms of line integrals, i s derived in this paper. Finally, examples for cones are presented and discussed. (C) 1997 Elsevier Science Ltd.
