Could someone tell me which ABAQUS subroutine would help extract SIF values of a crack in XFEM method? Do I have to use different subroutines for a stationary and propagating crack?
Abaqus has implemented the interaction integral and J-integral for XFEM for stationary cracks; i am not sure if there are also disposable for propagating cracks, but theoreticaley they should also work.
recently I proposed a new theory for fracture mechanics. in this theory the SIF may be explicitly and exactly be computed for any specimen. you may refer to the NED University journal of research and look for paper titled " Benchmark equations for..."2014; XI(3) :29-37
@Vincente: Which version of ABAQUS are you referring to? I'm not able to determine SIF for stationary cracks in 6.10 version.
@Adbolrasoul: I'll take a look! Thank you!
6.14, i do not remember since when is disposable but sure from 6.12
