RF-MAT NL Add-on Module for RFEM

Consideration of Nonlinear Material Laws

The RF-MAT NL add‑on module allows for consideration of nonlinear material behavior in RFEM.

  1. Material model - isotropic nonlinear elastic

    RF-MAT NL provides the following material models:

    Isotropic Plastic 1D/2D/3D and Isotropic Nonlinear Elastic 1D/2D/3D

    You can select three different definition types here:

    • Basic (definition of the equivalent stress under which the material plastifies)
    • Bilinear (definition of the equivalent stress and strain hardening modulus)
    • Diagram:
      • Definition of polygonal stress-strain diagram
      • Option to save / import the diagram
      • Interface with MS Excel
    Orthotropic Plastic 2D/3D (Tsai-Wu 2D/3D)

    This material model allows the definition of material properties (modulus of elasticity, shear modulus, Poisson's ratio) and ultimate strengths (tension, compression, shear) in two or three axes.

    Isotropic Masonry 2D

    It is possible to specify the limit tension stresses σx,limit and σy,limit as well as the hardening factor CH.

    Isotropic Damage 2D/3D

    This material model allows for a definition of asymmetric stress‑strain diagrams. The E modulus is calculated by Ei = (σii-1) / (εii-1) in each step of the stress-strain diagram.
