StructuralMaterialAssignment Properties

(To be removed) Structural material property assignments

StructuralMaterialAssignment will be removed. Use the MaterialProperties property of femodel instead. (since R2023a) For more information on updating your code, see Version History.

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

expand all

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

Data Types: char | string

Region ID, specified 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

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

Data Types: double

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

Data Types: double

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

Data Types: double

Coefficient of thermal expansion, specified 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

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

Data Types: double
