Fracture strain Vs. stress triaxiality ( ABAQUS Damage initiation )
Fracture strain Vs. stress triaxiality ( ABAQUS Damage initiation )
(OP)
Hello guys
I am trying to simulate a tensile test for 304 stainless steel flat specimen 50mm gauge length in ABAQUS. I have already done it experimentally in the lab using universal testing machine and now I have stress Vs. strain graph.
The problem now is I need to find fracture strain Vs. stress triaxiality for 304 stainless steel ( at any strain rate ) to use it in ABAQUS to set Damage initiation criteria. does anyone knows where to find these data or how produce them ?
Thank you

If anyone else has a good reference other than that, I'd be very happy to know it myself.
