So i am attempting to simulate the applied stresses on a plastic component connected to a fixed metal chain attachment with a bolt.
In operation there is a large force which pivots the plastic lug on the chain attachment and generates the crack seen in the image below.
I want to re-create this stress in a solid works simulation so i can modify the design of the plastic lug and then repeat the simulation and compare results.
However the results on Solidworks do not match. If i use global contact set as bonded there is no displacement visible where the cracks in the lug form. If i use global contact set as allow penetration the lug moves into the chain attachment but no displacement is shown.
I have attempted to run a fatigue analysis as in operation the high force is applied many times per minute. However i could not locate any SN cure value for polyurethane or alike.
Any help would be greatly appreciated! I'm new to the simulation world.
Thanks in anticipation.
