Based solely on the pic just up from the bottom one, it appears as if your load force is headed the opposite direction and you are showing compressive stresses.
Can you add a pic zoomed out? Also, if the blade & clevis are close it might be helpful to make them 'non-penetrating' so they don't run into/through each other or 'adhere'.
Ok. I made a test case to illustrate this point more clearly as in my original scenario I am doing something complicated things that I think would distract from the core issue.
What we have is 2 plates (3x2in) with a .75dia hole and a pin connector. They are separated by a distance of .06 inches (so bonding is not an issue). The bottom of one of the plates is fixed and the opposite plate has a 1000lbf axial load applied. Roller/slider conditions are on one of the thin-sides of each plate for model stability.
The stress from the pin connector is clearly being transferred into the part as if it is bonded to the hole's surface. IMO this connector and its documentation are grossly negligent as the stress distribution in vicinity of the connector will be wildly inaccurate.
I think this test case answers my question as to why the results were off. What else do users do to model this pin-clevis joints?
Oh, BTW, there is the BIG caveat for pin connections (the same for bolted connections) about the stress w/in a diameter being "off". This is an artifact of the rigid beam connection to the edge of the hole and the edge of the other hole.
