4.14.1.2. ElasticOrthotropic¶

nDMaterial('ElasticOrthotropic', matTag, Ex, Ey, Ez, nu_xy, nu_yz, nu_zx, Gxy, Gyz, Gzx, rho=0.0)

This command is used to construct an ElasticOrthotropic material object.

`matTag` (int)	integer tag identifying material
`Ex` (float)	elastic modulus in x direction
`Ey` (float)	elastic modulus in y direction
`Ez` (float)	elastic modulus in z direction
`nu_xy` (float)	Poisson’s ratios in x and y plane
`nu_yz` (float)	Poisson’s ratios in y and z plane
`nu_zx` (float)	Poisson’s ratios in z and x plane
`Gxy` (float)	shear modulii in x and y plane
`Gyz` (float)	shear modulii in y and z plane
`Gzx` (float)	shear modulii in z and x plane
`rho` (float)	mass density (optional)

The material formulations for the ElasticOrthotropic object are:
