Crack Paths 2006

C O N C L U S I O N S

In the present study, it is shown that crack paths can be followed without criteria for

neither crack growth nor crack path. An adaptive finite element procedure was used to

simulate the moving boundary of a body subjected to strain driven corrosion fatigue.

Results for kink angles due to mixed mode loading of a crack computed with the

presented criteria free method was found to agree well with predictions from criteria for

sharp cracks found in the literature. The best agreement was found for dominating

global KII loading, while for dominating KI loading the deviation was larger.

A numerical simulation of a surface crack in an elastic material growing towards a

stiff substrate demonstrates that the criteria free method can be used to investigate

features as crack deviation and branching.
