Thanks for your comment Brian,
It is true that theoretically stress at crack tip should be infinite, however, numerical solutions do not incorporate (1/r) or (1/sqrt(r)) singularity and therefore should converge to a finite value... Consider the attachment. In this attachment abaqus shows...
Hi,
I am currently modeling a stationary crack in a single edge cracked plate of hyperelastic material under mode-I loading with contour integral approach. I'm using quadratic elements without singularity control at crack front. The plate is loaded with prescribed displacements at plate...
