Add-on Module for RFEM 5
RF-MAT NL

The RF-MAT NL add-on module allows you to consider nonlinear material behavior in RFEM 5.

There is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (requires the RF-MAT-NL add-on module). This functionality enables simulation of the nonlinear strain behavior of ETFE foils, for example.

RF-MAT NL | Features

The following material models are available in RF − MAT NL:

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 σ_x,limit and σ_y,limit as well as the hardening factor C_H.

Orthotropic Masonry 2D

The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-directions of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.

Isotropic Damage 2D/3D

Here, you can define antimetric stress-strain diagrams. The modulus of elasticity is calculated in each step of the stress-strain diagram using E_i = (σ_i -σ_i-1 )/(ε_i -ε_i-1 ).
