Nonlinear material models are defined to represent elasticperfectly-plastic and elasticbuckling behavior. A simple three-bar truss is used to demonstrate that under a monotonically increasing prescribed displacement the truss may exhibit reverse stressing or non-uniqueness, and that when two different control displacements are applied the principal of superposition does not hold.
