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.

Abstract

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
