Well, as far as i know, CINT integration evaluates contour integral (in ansys help it is called Interaction integral) which is very similar to theory of J-integral. From this integration Ansys calculates J or K. KI, KII and KIII are separated with use of some auxiliary K-functions which are =1...
Thanks for answer, but i know that K is not valid for plasticity... i just thought that CINT command works similarly in elastic and plastic and the number value for CINT,SIFS should be evaluated to J even if it is not valid and doesnt mean the right value for plastic problem... i wanted to know...
Hello, I am using CINT command in Ansys v.14 to evaluate values of Stress Intensity Factors and J-integral. What is different between these two "types" of CINT command? Only change in input is in CINT,TYPE,JINT / SIFS... My problem is that theoretically there is relation between J and K (sifs)...
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...
