This command is used to construct an NDMaterial object which represents the stress-strain relationship at the gauss-point of a continuum element.
| ndMaterial matType? arg1? ... |
The type of material created and the additional arguments required depends on the matType? provided in the command.
NOTE:
The valid queries to any uniaxial material when creating an ElementRecorder are 'strain', and 'stress'. Some materials have additional queries to which they will respond. These are documented in the NOTES section for those materials.
The following contain information about matType? and the args required for each of the available material types:
- Elastic Isotropic Material
- J2 Plasticity Material
- Drucker Prager Material
- Plane Stress Material
- Plane Strain Material
- Multi Axial Cyclic Plasticity
- Bounding Cam Clay
- Plate Fiber Material
- Plane Stress Concrete Materials
- Contact Materials for 2D and 3D
- Wrapper material for Initial State Analysis
- Nonlinear, drained/undrained soil response under general 3D cyclic loading conditions (please visit UCSD for examples)
- UCDavis Soil Models
