I would like to know how to model a nonlinear spring with an arbitrar direction. The direction is changing during analysis. A file example would be very appreciated
In ADINA there are the possibilities to assign XYZ....direction only.
I try to model an elastic spring (say 1) which have a...
Hello! Can someone tell me how can I model a geometrical and material nonlinear spring element wich works along an arbitrary direction in a plane XOY? Thank you in advance!
I am doing an linearized buckling analysis using ADINA for a column-type structure. For the same model of the structure, with the same load, I am do two analysis. In the first analysis I ask two modes and 15 modes in the second. The results are different.
My question is what is the resason of...
