Abstract |
|
In this work, we have demonstrated a simple and robust means to implement the modeling of discontinuous fields with FEM technique. The FEM is used to study the crack modeling in isotopic and FGM. Issues pertaining to the selection of nodes for enrichment, computation of the enrichment functions, array-allocation for the enriched nodal degree of freedom, mesh-geometry interactions, and assembly of global stiffness matrix and external force vector are addressed. This study has provided the capability and revealed ease by which discontinuous fields through the partition of unity framework can be incorporated within a standard finite element package. |
