quasi static

Hi guys, I’m trying to apply on ABAQUS to do my MSc thesis, which is about a non linear buckling analysis of concrete filled tubes. In other words, I have to model on abaqus some compression tests of tubes filled with concrete, including initial deformations, contact properties and at the end load eccentricities. I read that to perform a quasi static analysis with nonlinearities the best way is the Dynamic Explicit Analysis, so I’m reading about that but unfortunately I have some doubts.

(in terms of the computational method)
