Modeling a Bending Moment Test
Modeling a Bending Moment Test
(OP)
I am trying to simulate a bending moment test on a pipe coupling assembly. I have attached a diagram of the moment test and also the assembly file. I am trying to model the test as accurately as possible, but encounter many errors when I think I am choosing the appropriate fixtures and connections and can't get any realistic results. The pipes, sleeve, ram, and base are made of steel and the couplings HYLON N1013 (similar to nylon 6/10). The ram pictured in the model can be suppressed if needed. Any help would be greatly appreciated!

RE: Modeling a Bending Moment Test
which errors do you get?
how have you constrained the pipe? Looking at the picture it seems like it is not constrained at all..
