Detailed Description

Propagation law that propagates the crack in the direction that gives .

Based on T.P. Fries and M. Baydoun: "Crack propagation with the extended finite element method and a hybrid explicit-implicit crack description", Internat. J. Numer. Methods Engrg 89, pp. 1527–1558 (2012)

The stress is evaluated in several points on a circle surrounding the crack tip.

Compared to the paper above, the implementation has been extended with a criterion for crack propagation instead of always propagating a predefined increment length. Two options are currently available for stress interpolation: 1) Take stress of closest Gauss point 2) Interpolate with radial basis functions
