Hi,
I think the problem is solved. I was considering wrong boundary conditions and inconsistent units.
In fact, this was just an exercice for me to familiarize myself with buckling simulation on Abaqus. Now,I intend to modelize the buckling of a composite sandwich beam (dimensions 16in * 2in)...
Sorry, this is the picture
TGS4: Can you explain me,please,how can I know the load at which the stucture will be plastic (using Abaqus)?
SWcomposites: Thank you for replying, but i really don't understand why if I put pressure it will bend not buckle(so what should I apply? Concentrated force?)
That means the buckling load in this case is 6456300 N = 6456.3 KN??? it doesn't seem logical I think...
The structure doesn't get plastic , it remains elastic until the critical buckling load.
Hi,
I am trying to simulate the buckling behaviour of an aluminium plate.So,i entered the dimensions of the plate in meter(0.41*0.25*0.0032) and the young's modulus in Pascal (70*10^9).
The boundary conditions that i applied are : *At the bottom :U1=U2=U3=0...
