Crack model according to DUGDALE
Fundamentals of the concept
DUGDALE's crack model was derived by WELLS in 1961 and is considered the basis for the Crack tip opening displacement concept (CTOD) concept of yield fracture mechanics. It is based on the assumption that with 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.
