摘要：

In order to obtain the Hertzian stress with high accuracy, very fine element division and enormous calculation time is needed for the FE & BE analysis. In addition, large-scale contact analysis to obtain accurate stress distribution, which is required to estimate strength of products such as turbine blade fixing on turbine disk, has been hardly possible. Authors developed a BEM program which include the following four techniques ; the p-version for the reduction of degree of freedom, the sparse method for the efficiency improvement of the calculation, the diagonal escalator method for the simultaneous linear equations, and the diagonal escalator method for iterative calculation. The performance of the developed program was verified by applications to demonstrative examples.
