RF-MAT NL | Features
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)
- 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 = (σi-σi-1) / (εi-εi-1) in each step of the stress-strain diagram.
