3.1.6. nDMaterial Command¶
This command is used to construct an NDMaterial object which represents the stress-strain relationship at the gauss-point of a continuum element.

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.
