Abstract
Fatigue and fracture parameters such as sigmoidal curve, fatigue crack growth threshold, stress intensity factor (SIF), and Paris constants are evaluated for thermo-mechanically processed Al-Mg (AA 5754) alloy at different stress-ratio. Experimental and numerical techniques are utilized for fracture and fatigue studies. Cryorolling and metal inert gas (MIG) welding processes are adopted to alter its mechanical and fatigue properties. The effect of cyclic stress ratio, thermo-mechanical processing, and MIG welding has been investigated on crack growth rate of the alloy. Extended finite element method (XFEM)-based program is developed to simulate both two-dimensional (2D) and three-dimensional (3D) crack geometries for quasi-static crack growth.
