I have created some simulation to investigate the behaviour of material (stress distribution) after the reach of yield stress. (My material model is defined by a measurement)
I have a simple measurement with a small part. After the bending of this part, I investiged with microscope the outside surface of part. I see the the material - along the bending radius - reach the yield stress. But the part was not broken...so I think that the stress doesnt reach the tensile stress. Insipte of this, in the simulation, as it can be seen below, the stress is in red area in full cross section along the bending radius....colored by red means stress is over tensile stress.
It seems to me that creo solver estimates over the stress distribution. It shows that the part will break but it did not happen in the course of my measurement.
What is the reason in your opinion?
Thanks
