Square plate under pure shear
Square plate under pure shear
(OP)
Question: In Patran, using NASTRAN as the solver, how do you load a square plate such that it is subjected to pure shear? I have a plate with a central hole, and am trying to demonstrate that the kt under pure shear is 4.
Any help is appreciated.

I think Kt = 4 for an infinite plate, so the hole should be “small” relative to the plate dimensions if you want to match that result. As the hole gets larger, the effect of the boundary increases and you’ll get a different result. The plate edges will not remain straight for that case, they will deform into an “S” like shape.
If you are planning to model a real problem eventually, you might consider applying enforced displacements around the perimeter rather than loads. This might be more appropriate if you’re looking at hole in a portion of a web which is bounded by stiffeners.

Using SW's approach, I got an answer within 1% of theoretical, so I am happy.
Thanks again.
