Dear All:
I completed calculating my stress-intensity factors by modifying the verification test case in ANSYS
I need to calculate the J-plastic values for Ramberg-Osgood type material using isotropic hardening for various n values .
Does ANSYS have a Ramberg-osgood material model built in ?
The only relevant benchmark codes that I can find in ANSYS help are :
1. J integral value for centered crack plate with BISO material model
2. J integral value for centered crack plate with elastic perfectly plastic material
I'm wondering which one of the above is relevant for Ramberg-Osgood type material using isotropic hardening ?
Any feedback is much appreciated .
