Hello, I'm trying to determine the critical torque required to buckle a hyperelastic cylinder after stretch and internal pressure utilizing the linear perturbation buckle feature. I will include my CAE file but basically I have a hyperelastic cylinder and I perform the following procedures in...

Thank you both...I will try out your suggestions

I want to stretch because the artery is typically at a stretch ratio of 1.5 in the body. Thus by stretching it they are more stable under internal pressure. Yes the plaque is given different material constants than the cylinder. So to summarize the cylinder should be stretched to mimic an...

Right now the tube is stretched (as a BC) before applying the pressure (plaque and all since they are drawn as one in solidworks). I want to be able to stretch the cylinder, then apply the plaque, and the lastly add the internal pressure.

of course...Here is what I have been doing (see attached file): Model a hollow hyperelastic cylinder to represent an artery with some type of material on the inside wall. This represents a stenosis (narrowing of the inner diameter, see attached file). Arteries are in a stretched state in the...

No it is actually more like plaque building up in a stretched artery. Thanks

Hello, I have a hollow cylinder that I would like to first stretch and then add material (like corrosion built up in a stretched pipe). My question is how do i add the material after stretching. This will be done in Abaqus 6.8 CAE Thanks!

what if you wanted to apply pressure first, then rotation. What would you use then? A constraint would not allow the diameter to increase so I am stuck with using connectors but don't know how to go about this...Thanks

I'm not sure if that is what it is but I think I need to use connectors instead of a kinematic coupling...Any idea as to what is the best way to approach this?

I am trying to apply rotation to one face of a cylinder. I am familiar with the kinematic coupling feature and can set a ref point as a control point and set the face of the cylinder as the constrained region (either as a node or surface works). I then apply rotation to the reference point as...

Hello, I am attempting to rotate a cylindrical shell. One face is fixed and I am trying to apply rotation to the opposite face. I first tried this by applying a BC around the axial axis to the desired face. I also tried applying a moment to this same face. This also did not work. This step in...

Here is what I have: A slightly curved hollow cylinder (curve to allow for imperfection) A reference point at each face with an applied kinematic coupling. All DOF are constrained. I first stretch the cylinder by applying the appropriate BC to each ref point. No problem I then want to be...

ok thanks a bunch for the info!

I am modeling a Fully incompressible 3D cylinder in Abaqus 6.8.3. I have chosen to use a tet element type. Once I am in the element type I then choose my geometric order as quadratic. I realize the hybrid box needs to be checked and it states "A 10-node quadratic tetrahedron, hybrid, constant...

This does help...thanks!
