I m modeling effect of composite fiber reinforce polymer (CFRP) layer on steel tube. There are some suggestion to model CFRP layer using truss element and to model steel tube using shell element. There is no problem modeling steel tube using shell element as the nature of thin wall...
Hi
I am simulating the effect of axial load on a square hollow steel tube. The problem comes up when the tube start folding to itself. I defined a double side surface which is the tube and using self contact as follow:
*Surface Interaction, name=Seft
1.,
*Friction, slip tolerance=0.005
0.1...
