Dear community,
I am trying to perform a tensile test simulation in ansys apdl . the test includes the Gurson damage model and the Chaboche plasticity model. however, when I run the analysis I get an error that says :
The stress updating does not converge for material 1 requested by element 600
anyone can give me a hint on how to solve this convergence problem
Ps: The code I wrote is attached.
Best
This part of the code seems strange to me:
Nsel,s,loc,x,-55e-3,-80e-3
D,all,all ! Define b.c. on node 1, totally fixed
Nsel,s,loc,x,55e-3,80e-3
D,all,UX,.5e-3 ! Define displacement on node 3, Ux=0.1
It seems like you are completely fixing all displacements of the nodes with x between -80e-3 and -55e-3 and then prescribing x displacement .5e-3 to the rest of the nodes. Is this intentional?
@Tomas yeah it is intentionally done cause the idea is to fix one end and apply a displacement on the other side for 100 step
