I am trying to turn a shaft in ABAQUS/Standard through contact forces on the shaft surface (i.e. a resultant moment on the shaft).
I am interested in the quasi-static state of the shaft (for example, how many radians for a given deformation of the contacting material).
The shaft is assumed to be placed on a perfect bearing with 1 rotational degree of freedom. ABAQUS/Standard always fail to converge. I am guessing this is because the moments don't balance out and there is rigid body rotation in the model.
I have managed to get a semi-rotating shaft by tying it to a spring/dashpot or an elastic-plastic material, but this will affect the result to some degree, so I am wondering if there is a smarter way of doing this.
I think this analysis is better suited for Explicit, but I am using UHYPER for the material model.
Any help would be appreciated.
