Stress intensity factors determination for an inclined central crack on a plate subjected to uniform tensile loading using FE analysis Paulo C. M. Azevedo IDMEC and Faculdade de Engenharia da Universidade do Porto March 2008 Abstract The stress intensity factors K I and K II for an inclined central crack on a plate subjected to uniform tensile loading were calculated for different crack orientations (angles) using finite element (FE) analysis, which was carried out in ABAQUS. The stress intensity factors were obtained using the J integral method and the modified virtual crack closure technique (VCCT). Good agreement between the results obtained with J integral method and VCCT was achieved. Both methods produced results for K I and K II which are close to the analytical solution. The effects of the boundary conditions were discussed. 1 - Introduction The plate is represented in Figure 1. Table 1 presents the dimensions of the plate and of the crack, the value of the applied stress and the properties of the material, which is considered elastic. The plate thickness is 1 mm, and the problem is considered bi-dimensional (2D).
