Hi,<\/p>\n

I have a composite tube of glass fiber and carbon fiber. I have set up the delamination problem in between these two layers by the Exponential for Interface Delamination Cohesive zone and I am twisting the two layers in two different directions on the open end. However, the solution always diverges whenever the twist angle reaches around 7.5 degrees regardless of how small the load stepping is. I am attaching the loading conditions here. z is the axis of the tube.<\/p>\n

I would be grateful if anyone here could help me with this issue.<\/p>\n

Thank you.<\/p>\n
