Hello all~
I was looking at a pin-in-socket lift-off hinge and the forces that might act on it. It lead me into thoughts regarding the tear-out stresses on the socket resulting from the moment load of the pin. Does anyone know how to calculate a simple version of this. I have created a solidworks model with a really basic version of what I am thinking. I am imagining the socket is fully fixed on the wide-flat flange in the geometry. I am also imagining a point-load on the end of the pin.
In my head, the failure mode would either be the pin bending or the socket tearing-out with a crack propagating from the open end of the socket towards the closed end of the socket as the pin pulls through the side-wall. Assuming a perfectly rigid ultra-strong pin, how would I calculate the tear-out stresses I am describing?
Attached are some screenshots to hopefully help with visualization.
Any help would be appreciated. Not super time-critical, as I can just go with a over-sized hinge at this point in time...but I want to understand these stresses for future designs and just because I hate not being able to calculate something.
Thanks!
