Finite-element fracture simulations using ZIP3D and critical CTOA fracture criterion on 7249 aluminum alloy have been made. Notch-strength analysis and fracture mechanics is explained. Comparisons have been made on the finite element simulation results and Two-Parameter Fracture Criterion (TPFC). Finite-element fracture simulations using ZIP2D (plane-strain core) and critical CTOA fracture criterion on 2219 aluminum alloy are presented and comparisons with Two-Parameter Fracture Criterion (TPFC) are made. Results from these comparisons illustrate the applicability of the TPFC to fracture analysis.
