Numerous material models are available in NairnFEA.
Define a Material
You create materials using a Material command block. Within that block all material properties are set using property commands. Refer to each material type to learn about its possible properties.
Linear Elastic Small Strain Materials
NairnFEA currently only has small-strain, linear elastic materials.
| Name | ID | Description |
|---|---|---|
| Isotropic | 1 | Linear elastic, isotropic |
| Transverse 1 | 2 | Linear elastic, transversely isotropic with unique axis in the z direction |
| Transverse 2 | 3 | Linear elastic, transversely isotropic with unique axis in the y direction |
| Orthotropic | 4 | Linear elastic, orthotopic material |
Interface Materials
Material Class Hierarchy
Materials are C++ classes. The following class hierarchy shows the orginzation of those C++ classes in NairnFEA source code. A material in green is an abstract class that is never assigned to elements. All others are material classes (by their name and their ID in parentheses):
- MaterialBase
- Elastic
- Isotropic (1)
- Transverse 1 (2) (2.3)
- Orthotropic (4)
- Elastic
