Keywords:

The stability of the equilibrium of rod systems is studied numerically taking into account the geometric nonlinearity using as an example a truss with rigid nodes. Various material models are used: linear elastic and elastoplastic with Prandtl and real stress-strain curves. The features of the loss of equilibrium stability are shown.
