Crack initiation
Initiation of a crack
Crack initiation is essentially the transition from a stationary crack to a moving crack. Starting from microdefects in the material volume, the resulting stress concentrations cause the fracture strength to be exceeded locally, thereby initiating a crack [1–2]. This is followed either by crack propagation or crack arrest. Crack initiation is often preceded by crack blunting (see also: fracture mechanics and crack resistance curve).
Fracture mechanics testing makes it possible to determine characteristic values that can be used to characterise the material's resistance to crack initiation [3].
