Hi all,
New to the forum.
I want to simulate a tensile test (Static structural test) of a threaded connection between 2 steel pipes.
The setup is: 2 pipes (with shortened length to reduce computing time), an X-axis force on one of the pipes and a frictionless support on the other.
The solver returns this error "The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information.". I've searched online but didn't find anything helpful.
I've also tried a 2d axisymmetric test but the results are odd.
The max equivalent stress point is calculated on the edge of the right tube while I expect to be located at the thread area. I've seen results of physical tests and the breaking/failure point is at the male thread. The other thing is that there is no stress on the left tube which is also incorrect according to me.
I would really appreciate any help.
Thanks!
PS Large displacement is turned ON. I'm using Ansys 14.5
