Modeling plastification

[sbrijesh]

hi,
I am trying to model the plastification in a railway wheel. My model consists of a rail(elastic) approximately 60mm length, a section(slice from a cake) of a wheel(plastic) .. approximately 5.5°. Now i want to perform a repeated process of rolling this wheel on the rail, ie. the wheel rolls and then is taken back to its origingal position, again rolls and again is taken back to the original position, I dont want any interaction between the wheel and the rail while the wheel is going back to its starting position. The only way i can think of is to raise the wheel vertically to some height(so as it looses contact with the rail) then translate it backwards and again put it down, it will work but sounds too complicated and long process!!! is there any shorter and more decent way of dealing with such problem. ABACUS/STANDARD Analysis!

It may be longer in that you'll need an extra step but better than having to remove the contact and finite sliding etc. in a step that you have no interest in the results and presumably don't wish to model. All you'd need is a step to lift and translate backwards then the next step will be the same as your initial contact step. Alternatively you can use a change model step which you remove the contact definition and then reimpose it later. That may be more complicated than just lifting and moving back.
