Hello
I am using abaqus riks to represent a behavior of honeycomb structure under compression
I want to compress half of the total length of the structure for example I gave displacement 10, total height of honeycomb structure is 20. It is not simple honeycomb structure so I imported geometry. It is 3D solid. I used tetrahedral meshes.
I assume there will be a buckling so I used Riks method but the problem is maximum displacement I got is only 3 but I want to see this strcuture collapse more. Even though I increased displacement, it still converges to the displacement 3.
When I visulize this, I could see in the beginning of increment steps, it is really compressed but it stabilize at some points during rest of steps.
My question is that how can I make this strcuture compress more with larger displacement.
Thank you
