4.15. nDMaterial commands

nDMaterial(matType, matTag, *matArgs)

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

matType (str)

material type

matTag (int)

material tag.

matArgs (list)

a list of material arguments, must be preceded with *.

For example,

matType = 'ElasticIsotropic'
matTag = 1
matArgs = [E, v]
nDMaterial(matType, matTag, *matArgs)
