Hi,
I have done cylinder buckling analysis and in that I have observed when I give a higher value for the maximum arc length, sometimes after buckling the LPF goes below zero and instead of inward buckle I see an outward buckle(which is not expected).
In your case, I believe the beam buckles...
Hi Lukasinski,
I think you probably might have figured by now, still I would like to share what I know. I'm also working on the Riks procedure.
I usually use 0.05 or 0.1 as initial arc length which means 5% or 10% of the load is applied in the first increment and I keep 0.1 or sometimes 1 as...
Hi guys,
I'm analyzing the the buckling of axially compressed cylindrical shells using riks procedure in abaqus. After analysis, when I plot the LPF vs displacement (radial displacement of a node in the buckle region) I notice some regions of abrupt variations and overlaps in the curve, which is...
Hello,
I'm working on the buckling of cylindrical shells subjected to axial loading. In my case the cylinder is resting on 4 columns, so there is a possibility of local buckling above the support. I'm carrying out the non linear analysis in abaqus using riks procedure.
The problem is when I...
