Experiments show that a mode II crack branches symmetrically under fatigue loading. The characteristics of a symmetrically branched crack in a shear stress field are analysed by FEM. Mode II fatigue tests are performed on six specimens of three different materials. Serious friction is observed exist

Crack growth is analyzed numerically under combined mode I, II and III loading, or under loading in one of these modes alone. The solid is a ductile metal modelled as elastic-plastic, and the fracture process is represented in terms of a cohesive zone model. The analyses are carried out for conditio
Double edge notched axial compression specimens taken from thick welded steel joints have been used to grow fatigue cracks under pulsating compressive loads at mean stresses up to 55% of that needed for general yielding. The redistribution of residual stresses during specimen preparation and during

Almost all load bearing components usually experience variable amplitude loading (VAL) rather than constant amplitude loading (CAL) during their service lives. A single overload cycle introduced in a constant amplitude fatigue loading retards fatigue crack growth and increases residual fatigue life.
