2層体の弾性接触問題に対する近似解法

抄録

In this paper, an approximate solution for the elastic contact problem between two-layered bodies is proposed. This solution is analytically derived by applying the Hertzian contact theory and assuming stress field in the two-layered body. As a numerical example, the elastic contact problem between a rigid cylinder and a two-layered elastic body, which is composed of elastic film and a semi-infinite elastic body, is treated. From the result, the effectiveness of the present solution is examined by comparison with the Hertzian contact theory and the theoretical solution of Gupta et al.
