Hello,
I’m trying to simulate buckling of a thin walled cylinder under external pressure. My model is a 36” OD open ended cylinder that is 5” long. I want to simulate the buckling caused by a pressure applied to the entire outside surface. I’m having trouble applying a fixture to the cylinder that doesn’t impact the buckling simulation. Can recommend or explain how to use a fixture that doesn’t impact the loading or end conditions?
Thank you
Are you trying to produce a visualization of what buckling of this cylinder may look like, or are your trying to predict the buckling behavior for structural reasons?
