Model Tensile Cracking in Soil with Coupled Meshless-FEM Method
- 1.6k Downloads
An adaptive, coupled method based on radial point interpolation meshless method (RPIM) and finite element method (FEM) is proposed for the simulation of tensile cracking in soil structure. Potential crack area in the initial FEM mesh is converted to RPIM nodes and refined for crack analysis. A crack tracking approach is adapted to model complex crack surface and eliminate node distribution bias. Numerical example is presented to verify the proposed method.
