A damage mechanics model is proposed to study the void growth and crack initiation. J2 incremental flow theory along with a damage variable is used to model the material behaviour in elasto-plastic regime. Large deformation (large rotation and finite strain) finite element analysis is carried out fo
Using the crack initiation measurements for notched specimens with various geometry (CT and axisymetric notched specimens) and different notch radii, we will try to determine the number of cycles to initiate a fatigue crack in the vicinity of stress concentration. ## NOMENCLATURE nominal stress a
