Hi everyone, I'm having a bit of difficulty interperting the results of an ANSYS model I'm currently running. This is of a small, thin piece of metal (0.018" in thickness, ~1"x1" length x width), that I am fixing at one end and displacing the other end ~0.015". Essentially this is a cantiliver plate. On the plate, near the fixed end, are a series of small holes. ANSYS reports that at the boundary of one of the holes, there will be a peak stress concentration of 180ksi. This is when plotting von mises stress. This is about 150ksi higher than what I think this piece can handle. Is there any way to determine if this piece will plastically deform in the area of the stress concentration, making the stress concentration a non-issue? On the other hand, is there some sort of rule-of-thumb to determine if initiating a crack could be a concern? Thanks in advance, and I'd be happy to provide any additional information.
