Using Nonlinear Elastic Material Model
Tips & Tricks
With the nonlinear-elastic material model in RFEM 5, you can calculate and carry out a stress analysis of surfaces and solids with nonlinear material properties.
During the calculation, this material model acts without plastic components. To compare, you can imagine a rubber-like model, which from a certain point on only deforms and is not subject to any appreciable increase of stress. If this material is unloaded, it returns to its initial state without showing plastic deformations. Thus, you can consider rubber, caoutchouc, or plastic materials with very high strain limits in a model.
