The most realistic way to simulate this will be to include the threads and define the appropriate "No Penetration" contact definitions. Fortunately, it sounds like the loads, constraints, and geometry of your system is such that you can take advantage of symmetry; specifically, you can use a 2D axisymmetry assumption. This will greatly reduce the computational time required to solve and converge on a good solution.
This is pretty much what I was going to say.
I'm a little concerned that this ignores the preload in this joint and makes it look less stiff than it really is. In other words, this should be pretty conservative.
We've done this a couple of times for one of our oil and gas customers. 2d, no pen.
To deal with preload, we used thermal expansion of a small section.
Simplifiying to an axisymmetric model with the full thread detail seems to work, thanks.
Sorry for using this old thread but it's very similar to my case.
I have an assembly with two steel pipes joined with a threaded connection. I want to simulate the axial tensile and compare the results with the ones from an actual physical testing performed in a lab. Generally the observations are that all joints failed in the male threaded section of the joint.
Could you please outline me the steps to follow for this simulation?
PS Due to license limitations 2D simplification is not available so I prefer a static simulation (if possible) no matter it's more time consuming.
