PhanthomJay thank you for replying. I did a double shear test on 3/8 in rod of C1215 steel. I've attached the image I think. On the top and bottom of the rod the surface has noticeably yielded as if it has been cut into. are contact stresses a factor as well as avg shear stress. I'm trying to...
Hello everyone, I've been messing around with FEA and I'm trying to match my simulation with hand calculations. While doing this it occurred to me that i really don't understand why we use avg shear stress instead of maximum shear stress when determining the safety factor of a structural member...
