We talked about calculating J-integral and K1 using XFEM in the last post. XFEM is a powerful method as it eliminates the need to remesh crack-tip regions. However, there are some limitations. For example, material behaviour is assumed to be linearly elastic. The available fracture criteria are valid only for cracks in homogeneous linear elastic … Continue reading 2D Stationary Crack Analysis: J-integral and Stress Intensity Factor Calculation
