Description¶
The linear-truss domain is used for modeling linear trusses. It requires the linear truss material.
This domain uses the Kirchhoff stress and the logarithmic strain to construct the internal forces.
\[
\tau = E \, \log \left( \lambda \right)
\]
where \(\lambda = L_t / L_0\) is the stretch in the truss.
