Re: Help with Inelastic Column Buckling with Material Nonlinearity

Hi Joe,

Thanks for sticking through this and helping me out. 

 

I too found out earlier today that perturbing the model via nodes offset/move might be a better way of introducing imperfection rather than an end moment. 

 

I recently discovered that convenient API to move nodes by deformation. 

 

I can feel a resurgence of energy and try to move on to more advanced NL buckling i.e. plates and ultimately stiffened panels. 

 

Appreciate your help.
