What Ansys Element Models Tension-Only Cables with Hyperelastic Materials?

[Liub]

Hi,

What element should I use to model a tension-only (no bending stiffness) cable/chordae?

The problem is that I need to use a hyperelastic material model with it.
And LINK180 does not support the hyperelastic material model.

Thanks!

Have you looked at LINK10?

LINK10 is a three-dimensional spar element having the unique feature of a bilinear stiffness matrix resulting in a uniaxial tension-only (or compression-only) element. With the tension-only option, the stiffness is removed if the element goes into compression (simulating a slack cable or slack chain condition).
