HOW TO FIND K-DOMINANT REGION
hii all..
i am working on fracture mechanics. i had modeled a 4 pt bend specimen having single notch crack(in ABAQUS). i am trying to find the range of K-dominant region at the crack tip.i had modelled radial mesh at the crack tip and using 20 noded reduced integration elements. To analyze the K-dominat region, primarily i had compared the theoritical stress plots and computational stress plots. stress plots means Sxx Syy Sxy values plotted againt the angle(angle measured from uncracked segment) at particular radius.
i request your suggestions, relevent papers and comments.
thanks
best wishes

A famous paper
Dear Mr. Ravitej,
Check this paper:
Rosakis, A.J. and Ravi-Chandar, K. 1986. On Crack-Tip Stress State: An Experimental Evaluation of Three-Dimensional Effects,” International J. of Solids and Structures, 22, 121-134.
thank you

dear luoyu roy xu
thank you. this paper seems to be an experimental paper. can you suggest me any computational paper to fine K dominance.
cheers
