Load Increments and Nonlinear Materials

Helpful Questions & Answers

  • Frequently Asked Questions (FAQs)

Is it possible to set load increments, save each step results, and view at which load increment the material is yielding?

Answer

To activate the nonlinear material behavior in RFEM 6 or RSTAB 9, the Nonlinear Material Behavior add-on must be activated.

The material model should then be modified from the default setting "Linear Elastic" to the relevant "Plastic" setting under the Material dialog box depending on if the element is a 1D member, 2D surface, or 3D solid.

Lastly, the Static Analysis Settings should further be modified to set the number of load increments and to activate the saved results of all load increments checkbox.

After the calculation, all results can be viewed in the Navigator - Results panel by the load increment selected.
