The second order manifold method with six node triangle mesh

Abstract

The manifold method is a recently developed numerical procedure. Based on the original first-order Manifold Method, the second-order one together with corresponding computational code is developed in the present paper. Application examples include calculation of stress distribution of a circular ring, analysis of contact stress of a cylinder compressed between rigid plates, large deformation problem of a cantilever and failure of a slope with discontinuities. The results show that the second-order manifold method is capable in analyzing structure deformation and contact problems with relatively high accuracy and has priority in simulating large deformation problem and failure process.
