Meshing technique for compression of hollow cylinder

Meshing technique for compression of hollow cylinder

Meshing technique for compression of hollow cylinder

(OP)
Hi,

I am working on a project where I am a trying to model an artery that is being compressed by a machine, I am trying to create the mesh in abaqus and export it to a program called FEBio, another FEA program to run the actual analysis. The problem is I am consistently running into negative jacobians in all the simulations. From what I have found on the internet it seems like negative Jacobiains are caused by poor mesh quality for the simulation in which I am using a rigid body to push the hollow half cylinder inwards. I am very new to FEA and meshing and am looking for any advice on how to simulate this or create a higher quality mesh that will not give a negative jacobian.

Thank you

RE: Meshing technique for compression of hollow cylinder

Hi calxx,

never came across errors with negative jacobians...

but, have you taken a look at the Abaqus documentation for modelling arterial layers? Checkout:

Abaqus Benchmarks Guide -> 3 Material Tests -> 3.1.7 Anisotropic hyperplastic modelling of arterial layers

from the documentation you access .inp files. hopefully this will put you in the right direction.
