__FORCETOC__

==Initiation of a crack==

Crack initiation is essentially the transition from a stationary [[Crack|crack]] to a moving crack. Starting from microdefects in the [[Material & Werkstoff|material]] volume, the resulting [[Fracture Mechanics|stress concentrations]] cause the fracture [[Strength|strength]] to be exceeded locally, thereby initiating a crack [1–2]. This is followed either by [[Crack Propagation|crack propagation]] or crack arrest. Crack initiation is often preceded by [[Crack Opening|crack blunting]] (see also: [[Fracture Mechanics|fracture mechanics]] and [[Crack Resistance (R) Curve|crack resistance curve]]).

[[Fracture Mechanical Testing|Fracture mechanics]] testing makes it possible to determine [[Material Value|characteristic values]] that can be used to characterise the material's resistance to crack initiation [3].
