Numerical Modeling of Crack Growth under Mixed-Mode Loading

The aim of this paper is to simulate the propagation linear elastic crack in 3D structures using latest innovation developed Ansys software, which Separating Morphing and Adaptive Remeshing Technology (SMART), order enable automatic remeshing during a simulation fracture behaviors. ANSYS Mechanical APDL 19.2 (Ansys, Inc., Canonsburg, PA, USA), used by employing special mechanism ANSYS, smart growth method, accurately predict paths associated stress intensity factors. For accurate prediction mixed-mode factors (SIFs), interaction integral technique has been employed. This approach for SIFs three-point bending beam, six different configurations: three configurations with holes, other without holes involving mechanics (LEFM) assumption. results indicated that was attracted hole changes its trajectory reach or floats grows when missing. verification, data available open literature on experimental path trajectories were compared computational study results, very good agreement found.
