Why is my LPF in Riks method greater than the critical load factor in Buckling analysis?
Why is my LPF in Riks method greater than the critical load factor in Buckling analysis?
(OP)
I have conducted buckling analysis in order to obtain the critical load and the initial imperfection shape for the next step, which is Static, Riks. After the analysis, as a result i get that the Load Proportionality Factor shows that the maximum load is greater than critical load from buckling step. I am modeling a beam (channel tube) and i am using shell elements. Can anybody help me with this?
