non linear geometric

[albert1981]

Hallo everybody,

I want to try to make a non linear geometric analysis with abaqus. I have a distribution of stresses and I would like to apply a Load step by step in order to see how the load is going to redistribute the stresses every step.
Is it possible to make a non linear for different step load?
I try to search on guide but I didn't find nothing helpfull.

Thanks,
Albert

Just put NLGEOM as an option on the *step card.

Dear corus,

thanks for the advice. I would like to ask if there is a way to apply different load with the step. what I want to do is make a first step with a certain load and the following step with another load that is applied to the previous deformed shape. I try but it give me only separete cases without considering the effects of the previous step. I am doing something wrong?

Thanks again,
Albert

The load is always applied to the previous results. I'm not sure how you've managed to reset it so that it doesn't consider the previous results.
