Abstract:
A new technique of mesh generation used in tracing the crack propagation with adaptive FEM was provided. The method will simulate the crack propagation dynamically by modifying the shape and the neighboring connection. This method has the advantages such as narrower modifying area, more realizable, needless of changing the element type, and so on. A numerical example shows the provided method is effective.
Key words: adaptive mesh refinement, crack propagation, neighboring connection
