FEDEAS structures library consists of several uniaxial stress-strain relations. These are classified presently into four groups for identification purposes:
 | Concrete material models |
| Reinforcing steel material models |
| Hysteretic material models |
| Bond material models (no manual pages yet) |
Any of these models can be assigned to a fiber or section force-deformation relation. These models can also be combined in series to create complex composite models for section force-deformation relations.
Material models are specified in FEAP following the FEDEAS custom keyword ML1D during the MESH input phase.
| ML1D up to 4 input lines for each material model as specified in the manual pages terminate ML1D block with blank line |
Note:
Number of material models in an input file is limited to 25.
Thus, matID can be any number between 1 and 25 for each material model.
Most material parameters have reasonable default values. If you are not sure about a parameter value, leave the field blank. The program will echo the default values in the output.
