MATERIAL

The MATERIAL statement defines a collection of constants appearing in the constitutive equations (stress-strain equations) for a linear elastic material.
The constants are grouped depending on the form of the constitutive equations. For instance, a linear orthotropic material used in flexural beams, has a particular type of constitutive equation requiring a relation between and only.

Format

MATERIAL/id
 
, NAME = s
, DENSITY = r

Arguments

 
ANISOTROPICBEAM=c11, c12, c13, c22, c23, c33
Specifies the elastic constants of the stress-strain relationship in flexural beam elements having a general linear elastic anisotropic material.
ORTHOTROPICBEAM=E, Gxy, Gyz
Specifies the elastic constants of the stress-strain relationship in flexural beam elements having a linear elastic orthotropic material.
NAME=s
Indicates a name for the material.
YOUNGS_MODULUS=E
Specifies the Young's modulus of a linear isotropic elastic material.
POISSONS_RATIO=
Specifies the Poisson's ratio of an isotropic elastic material.
DENSITY=r
Specifies the density of this material.
 
Note:  
A MATERIAL statement is required in models having one or more FE_PART statements. FE_PART statements are used to define embedded Finite Elements in Adams.
