Hi,
Is there a way to define a spring (pure tension spring) with an E-Modul and an Area instead of using the spring-constant k? I know, it is possible to calculate k with E*A / L_0 but I try to be independent of my L0 value.
Thanks, Regards
Jonas
Hi Jonas,
I don't think it is possible. In all the springs defined K value has to be provided.
Can I use beam-elements instead and use them as a spring (so that they only work in tension)?
Regards, Jonas
Yes, you can model with beam elements.
Or would trus-elements work better as they are used only for axial forces?
Is there a tutorial on this?
Truss elements are a subset of beam elements which have no bending degrees of freedom. Truss elements transmit force axially only. That is, these elements allow translation movement only and not rotation. Truss elements are normally used in conditions where no bending is expected.
You can go through Example 7 - Pendulums in the Help Menu where truss elements are used. The model file is attached for your reference.
