Spherical Expressions of Element Matrices for Finite Element Covers in Numerical Manifold Method

    Abstract
  • In order to simulate crustal deformation in large scale,a 2D spherical NMM is developed from plane NMM.The new model adopts spherical triangles as mathematical covers.The stiffness matrix,initial stress matrix,point load matrix,body load matrix,inertia force matrix are derived,which lay a foundation for the new model.
