Good day,
I have a simulation of 3D crack in Ansys Workbench 12.1 and I need to calculate Stress Intensity Factors. I used command CINT and my results looked good (expected numbers, extremes in assumed places etc.), until I saw the same simulation with only one difference. The other simulation was made in older version of Ansys and with use of KCALC command instead of CINT calculation. But the results were different! Main problem was that in my simulation, K2 and K3 extremes were almost the same, but in older simulation they K3 was twice as K2. In Ansys help I read that KCALC uses displacement extrapolation and CINT uses contour integral calculation, but I think they should show the same results if they are applied on the same model with same conditions.
Any idea where should be problem? It would help me much beacouse I found nothing on internet or in Ansys help manual.
Thanks everyone.
