Which Element to model STEEL CABLE? Please help!

[richonlinedeal]

Hello, Deal All,

Can anybody give me some hints which type of elements I should use to model Cable in ABAQUS? The cable could have different stiffness. Should I just use different E (Young's modulus) values to simulate this different stiffness? Thanks a lot.

Have a look at the "*No Compression" keyword (also in CAE, Material Options).

This can be used with just about any elastic element, but watch out for convergence problems.

Thanks alt MrMyers for this info. Cheers!

Hello, MyMyers/All,

Forgot to ask you one more Q: If the Steel Cable is mainly to sustain Axial Tension but can bear little or no bending moment, is there any special Element I should choose? ALso, should I set the cable material to have a small Young's Modulus to achieve this? Thanks again.

Jerry

You can use truss.

 

[MrMyers]

Or even hypoelasticity, with a very low modulus for strain in compression and a normal Modulus for strain in tension?

Using Truss element to model cable is hard to converge often.
