hi i need help with my analysis,am doing a buckling analysis and i will like to know how to plot a graph showing displacement against force.....please help me i have been stuck with this for 2 months now please...somebody help

Hi

from my understanding, the buckling analysis is a transformed eigenvalue solver and hence gives only a "security factor" w.r.t an intial load, when buckling will occur.

The other way to load up to a buckling is to explicitely increase a load and record the displacement, or impose a displcement and record the reaction forces (use large deformation)

Good luck

Hi
Please in an attempt to apply vary loads so i get the displacements in order to plot the graph i think i messed up the whole buckling analysis please help me i have to submit this to my lecturer on Tuesday 6th Dec. Please help me ....i have attached my analysis could you please check it out for me and really stuck....
