SMART crack growth - critical crack length
I'm running a fatigue cycle on a hollow cylinder of shell thickness 40mm, with a Semi Elliptical Crack on the surface.
My SMART crack model runs up to a crack extension of 24mm after a cycle of ~77000 cycles, at which point the model stops.
Has it stopped at 24mm as the software believes this is the critical crack length? or because it's met some other parameter?
I have not set a predetermined crack length or time for the model to stop.
Any help appreciated.
