findStructuralProperties

Find structural material properties assigned to geometric region

Description

example

smpa = findStructuralProperties(structuralmodel.MaterialProperties,RegionType,RegionID) returns the structural material properties assigned to the specified region. Structural properties include the Young's modulus, Poisson's ratio, and mass density of the material.

Find Young's modulus and Poisson's ratio for cells of a 3-D geometry.

Create a structural model.

structuralmodel = createpde('structural','static-solid');

Create the geometry consisting of three stacked cylinders and include it in the model. Plot the geometry.

gm = multicylinder(10,[1 2 3],'ZOffset',[0 1 3]);
structuralmodel.Geometry = gm;
pdegplot(structuralmodel,'CellLabels','on','FaceAlpha',0.5)

Assign different values of the Young's modulus and Poisson's ratio to each cell.

structuralProperties(structuralmodel,'Cell',1,'YoungsModulus',200E9, ...
                                              'PoissonsRatio',0.3);
structuralProperties(structuralmodel,'Cell',2,'YoungsModulus',210E9, ...
                                              'PoissonsRatio',0.3);
structuralProperties(structuralmodel,'Cell',3,'YoungsModulus',110E9, ...
                                              'PoissonsRatio',0.35);

Check the structural properties specification for cell 1.

mC1 = findStructuralProperties(structuralmodel.MaterialProperties,'Cell',1)
mC1 = 
  StructuralMaterialAssignment with properties:

       RegionType: 'Cell'
         RegionID: 1
    YoungsModulus: 2.0000e+11
    PoissonsRatio: 0.3000
      MassDensity: []
              CTE: []

Check the structural properties specification for cells 2 and 3.

mC23 = findStructuralProperties(structuralmodel.MaterialProperties,'Cell',[2,3]);
mC2 = mC23(1)
mC2 = 
  StructuralMaterialAssignment with properties:

       RegionType: 'Cell'
         RegionID: 2
    YoungsModulus: 2.1000e+11
    PoissonsRatio: 0.3000
      MassDensity: []
              CTE: []

mC3 = mC23(2)
mC3 = 
  StructuralMaterialAssignment with properties:

       RegionType: 'Cell'
         RegionID: 3
    YoungsModulus: 1.1000e+11
    PoissonsRatio: 0.3500
      MassDensity: []
              CTE: []

Input Arguments

Material properties of the model, specified as the MaterialProperties property of a StructuralModel object.

Example: structuralmodel.MaterialProperties

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

Example: findStructuralProperties(structuralmodel.MaterialProperties,'Cell',1)

Data Types: char | string

Geometric region ID, specified as a vector of positive integers. Find the region IDs by using pdegplot.

Example: findStructuralProperties(structuralmodel.MaterialProperties,'Face',1:3)

Data Types: double

Output Arguments
