Abstract

This paper proposes a combination of FRANC2D/L (2D crack growth simulation program) and ANSYS mechanical program (3D structural analysis for fracture mechanic analysis. The comparisons between the two software were performed for different case studies for stress intensity factors (SIFs) as well as crack growth trajectory. Crack growth was numerically simulated by a step-by-step 3D and 2D finite element method. The SIFs were calculated by using the displacement correlation technique. The procedure consists of computing SIFs, the crack growth path, stresses, and strain distributions via an incremental analysis of the crack extension, considering two and three-dimensional analysis. The finite element analysis for fatigue crack growth was performed for both software based on Paris's law as well as the crack orientation was determined using maximum circumferential stress theory. The simulation results obtained in this study using finite element method provide a good agreement with experimental results for all the case studies reviewed.
