Abstract Studies of crack growth in fatigue of annealed aluminium, Nylon 66 and Araldite epoxy resin have revealed two mechanisms, shear and tensile tearing. The former applies both to fatigue and to tensile straining under approximately plane strain conditions and requires a capacity for plastic flow within the material. The latter mechanism occurs where flow is either restricted or impossible. A model for crack propagation in low endurance fatigue is described, and a rigid-plastic analysis is shown to be consistent with the observations.
