No Compression Spring Elements
No Compression Spring Elements
(OP)
Hi,
I am currently working on creating a finite element model of the cervical spine and in Abaqus I am trying to model the ligaments in that region using spring elements. Does anyone know how exactly, whether through the CAE or editing the input file itself, that I can create tension only spring elements? If so I would greatly appreciate it.
Thanks

How exactly do I use CAE to create tension only springs? When I create the springs using the GUI there is no option to assign tension only, there's simply a space to enter a value for the stiffness of the spring.

I didn't find it. I don't have Abaqus help installed but even searching in the internet I can't find the solution. I'm asking because probably CRAD3820 has already done it. Am I right? Please if someone knows how to do it please help me.
My question is the same of CRAD3820: Does anyone know how exactly, whether through the CAE or editing the input file itself, that I can create tension only spring elements?
Thank you!!

you should use CONNECTOR UNIAXIAL BEHAVIOR. This capability is not available through Abaqus/CAE so you have to edit the .inp file. Moreover, this option is only available for Abaqus/EXPLICIT.
Try to search in Google, there are some inp's which you can use as example.
Kind regards,
Julio
