An Element Splitting Algorithm for Crack Propagation
A new algorithm is presented for the finite element analysis of fracture mechanics. The algorithm allows crack propagation in any direction, and guarantees the crack path smoothly. This is achieved by tracking the path of the crack tip and by introducing a new remeshing method. Examples show that this algorithm is efficient for 2D problems.
