StructuralMaterialAssignment Properties

Structural material property assignments

A StructuralMaterialAssignment object contains the description of material properties of a structural analysis model. A StructuralModel container has a vector of StructuralMaterialAssignment objects in its MaterialProperties.MaterialAssignments property.

To create the material properties assignments for your structural analysis model, use the structuralProperties function.

Properties of StructuralMaterialAssignment

RegionType — Region type

'Face' | 'Cell'

Region type, returned as 'Face' for a 2-D region, or 'Cell' for a 3-D region.

Data Types: char | string

RegionID — Region ID

vector of positive integers

Region ID, returned as a vector of positive integers. To determine which ID corresponds to which portion of the geometry, use the pdegplot function, setting the 'FaceLabels' name-value pair to 'on'.

Data Types: double

YoungsModulus — Young's modulus

positive number

Young's modulus of the material, returned as a positive number.

Data Types: double

PoissonsRatio — Poisson's ratio

positive number

Poisson's ratio of the material, returned as a positive number.

Data Types: double

MassDensity — Mass density

positive number

Mass density of the material, returned as a positive number. This property is required when modeling gravitational effects.

Data Types: double

CTE — Coefficient of thermal expansion

real number

Coefficient of thermal expansion, returned as a real number. This argument is required for thermal stress analysis. Thermal stress analysis requires the structural model to be static.

Data Types: double

HystereticDamping — Hysteretic damping parameter

nonnegative number

Hysteretic damping parameter, returned as a nonnegative number. This type of damping is also called structural damping.

Data Types: double
