Dear Users,
I'm perform some calculations in abaqus/standard with objective of evaluate stress intensity factor K1 through J Integral Method.
I Use triangular quarter point elements (STRIA65) sorrounding the crack tip to represent properly the singularity (1/sqrt(r)) around the crack tip but my simulation shows an error after first increment in *.msg file:
Contribution to contour integral for 16 elements is not included. The elements have been identified in element set ErrElemContribJIntegralStep1Inc1.
The following card has been used in the code:
*Contour Integral, crack name=H-Output-1_Crack-1, contours=5, crack tip nodes, type=K FACTORS
N_crack, N_crack_tip, 1., 0., 0.
Somebody can help me?
Best Regards
