Crack model according to DUGDALE
__FORCETOC__

==Fundamentals of the concept==

DUGDALE's [[Crack Models | crack model]] was derived by WELLS in 1961 and is considered the basis for the [[Crack Tip Opening Displacement Concept (CTOD) | Crack tip opening displacement concept]] (CTOD) concept of yield [[Fracture Mechanics | fracture mechanics]]. It is based on the assumption that with [[Ductility Plastics | ductile]] material behaviour, the fracture process is controlled by a critical plastic deformation, the crack tip opening displacement CTOD or crack opening ''δ''.

The formation of the plastic zone rpl depends on the microstructure and therefore cannot be represented in a generally valid form. Deviating from the modelling of the theoretical concepts of fracture mechanics, material-specific plastic zones are demonstrated experimentally.
