| Abstract: | This paper concerns the boundary contour method ( BCM) of 2-D elastic problems. This method is based on the equivalent boundry integral equation. The cubic shape functions are used and numerical implementation is presented. The mixed collocation of the formulations of the BCM is presented for the mixed boundary value problems. The present method is shown to give excellent results. |
