Can i use noseparation contact for large and small sliding in Static analysis.

Hi,

I am trying to solve a shaft and cylinder kind of problem in static analysis. Can I see the movement of the cylinder using static analysis or should I have to use transient analysis?

As i was instructed to use static analysis since only small sliding is possible in my analysis. But when i use no separation contact in my simulation i can not observe any displacement. Can anyone please let me know what is the problem.

    You would only need to run a transient analysis if inertia effects (acceleration of mass and damping over time) are significant.

    It is hard to say why your results are not as expected. No separation is a linear contact behavior where status will always be closed and sliding.

    Perhaps you need to turn on Large Deformation or perhaps your loading and constraints are not correct.

    Thanks for your response.Now i have understood when to use transient analysis.
