Subinterfacial Crack Growth in Bimaterials
Abstract
The algorithm is discussed and a program is developed based on X-FEM in this chapter for simulating subinterfacial crack growth in bimaterials. Numerical analyses of crack growth in bimaterials give a clear description of the effect on fractures made by the interface and loading. Computational results are compared with experiment data, which shows that X-FEM is more powerful in capturing the actual crack path than standard FEM. Further results show that there is an equilibrium state of mode I cracks in bimaterials if the effects of material inhomogeneity and loading asymmetry counteract each other.
