A DEVELOPMENT OF BEM TO TWO DIMENSIONAL ELASTICITY

This paper presents a new boundary integral equation for two-dimensional elasticity with the stress component _ij t _i t _j as one of the boundary values, wheret _i is the direction cosine of the tangent on the boundary. This form of BEM has an advantage in that the stress component _ij t _i t _j on the boundary can be calculated directly from the numerical solution. The present formulation for plane problems uses two kernels, the one is logarithmically singular and the other is 1/r singular. The effectiveness of the approach is also discussed through test examples.
