Creating Elastic-Plastic 2D/3D Material Model
Tips & Tricks
The elastic‑plastic material model in RFEM 5 allows you to calculate surfaces and solids with plastic material properties and to carry out a stress evaluation. This material model is based on the classic von Mises plasticity.
One advantage of the elastic-plastic calculation in RFEM is the calculation time and the number of necessary iterations. Furthermore, the material can now save plastic distortions or deformations in every load increment and use them for the next calculations steps. With this material behaviour, it is thus possible to take into account the loading and unloading of a material, whereby the plastic deformation in the material is preserved.

Frequently Asked Questions (FAQ)
- When defining my material, I get Warning No. 1136 and cannot continue working. How can I prevent this warning?
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- I would like to use surface releases to model a bolt connection, which can only absorb compressive stresses from the support. Unfortunately, I cannot do this because my model is always unstable. Is there a model as a template?
- Why is it not possible to change the solving method for the equation system of my model?
- How can I incrementally apply the load of a load case to the model?
- After importing an .stp file, my model is unstable. What can be the reason for this?
- When entering a new material using the Diagram definition type, the first row is locked. How can I define the material?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- Can I define nonlinear supports by using tables?
- Where can I find the RF‑CONCRETE NL add-on module? How can I activate it?
