Coupling of level set and meshless method and its application to crack propagation

A new method which couples the level set method with meshless method to simulate crack growth is presented.The coupling of level set and meshless method can achieve naturally because they all set up based on the discrete nodal data.Two level sets that are orthogonal to one another at the crack tip are used to represent the geometry of crack and the location of crack tip,and to construct the Heaviside skip function and the Westergaard enriched...
