Abstract

The numerical manifold method (NMM) is a combination of the finite element method (FEM) and discontinuous deformation analysis (DDA) method. It provides a robust numerical solution to a solid medium with dense discontinuities. This paper extends the numerical manifold method to the three dimensional domain from the fundamental concepts. It explains the three essential entities, i.e., the mathematical cover, the physical cover and the manifold element in the 3-D version under the framework of the finite cover system. Furthermore, it tests the robustness and accuracy of the proposed algorithm through a tetrahedral wedge sliding simulation in a rock slope.
