Hello,

AutoCad has an FEA program that can be used for stress analysis. I am very interested in how to model a raised faced flanged joint using this program. The FEA is a simple program for applying loads and constraints to a single solids model. Only one solid model can be done at a time. So the both flanges that make up a joint cannot be modeled. Gap elements are not available in this version of the FEA.

I have been simulating the gasket loading, face contact and bolt loading with pressure applied to the applicable surface of the flange. The gasket loading is applied to the surface where the gasket makes contact, the metal face has a contact pressure applied. An area around the bolt holes has been defined for a pressure to simulate the bolt loading.

Does any one else have experience in this area?

Thanks

Well i have also tried thay by using ansys. Its realy difficuilt to encounter gasket effects.
U may try a software for it "AXI PRO" of PRG.
