ramp or step input?

[maxibonne]

In a static structural non-linear analysis, what difference is there between applying a load as a step or a ramp with 'kbc' in ansys ?

Does it affect results?

I think that in a non-linear analysis, the load is is usually ramped up. That means that the load will be gradually applied depending on the number of increments specified. For example if one specifies only one increment in a non-linear analysis, the anaylysis may not converge.

What do you mean by static?

in my opinion,if you use the step loading method in the analysis,"force quiver" maybe happen to it.
