The theoretical study is advanced to describe quantitatively the crack propagation under cyclic loads. The main assumptions accepted are: (a) a crack grows by loading during every cycle, and (b) the specific dissipation energy is a material constant. The latter contains. the known concept by Irwin a
In this paper, based on physical meanings of hysteresis loops denoting a relationship between loads and strains near the fatigue crack tip, variations of the tensile plastic zone in loading and the compressive plastic zone in unloading as well as the effects on acceleration, retardation and non-prop
Crack propagation experiments were performed on a mild steel side edge notched specimen for various load ranges and stress ratios at constant maximum loads. The life of the specimen increased as the load ratio increased. The crack growth data were analysed in terms of AKeff as a function of stress r
Fatigue tests have been carried out on edge notched mild steel specimens of various thicknesses. Results are presented showing the effect of thickness on crack initiation, crack growth and the geometry and fractography of the fracture surface. It was found that both crack initiation and crack growth
