So you think modeling with frictionless contact is too conservative to assess if there is any separation and to calculate margins on bolt strength? My concern is that modeling everything as bonded is too unconservative. I'm much less concerned about gapping because this is a very stiff joint, so...
I might not be on the same page as you, but I was thinking I need to apply the shock load to assess first to see if my assumptions of preload and contact hold. Then I solve the model with fasteners, and the model without fasteners.
I am modeling with solid elements because this is a relatively small assembly and I want maximum accuracy. Preload is included. I haven't heard the term contact elements before - when I say contacts, I would categorize them as boundary conditions in ANSYS. A bonded contact between two interfaces...
Thanks for the reply. I agree that a gapped joint is a bad design, but I should confirm that right?
I would ideally use only one model to save time and work, but I think the only option to do that is to use a frictional contact. I think this is the most accurate way of representing the...
I need to do a shock analysis on an assembly that can be simplified into a fixed plate with tapped holes, and a cantilevered beam with a flange bolted to the plate. My objective is to find stresses in the bolts and the beam. I am using ANSYS Mechanical to solve this problem. The system is setup...
