Temperature - Dependent Material Properties

You can define temperature-dependent material properties. Instead of a constant value, a material property is defined by pairs of temperature and property values in the desired units. The specified variation is saved in the library for repeated use. You can define a curve manually or import an external file.

The value entered in the Value column is ignored if a curve is defined for the property.

To define a temperature-dependent material property:

  1. In the Simulation study tree, right-click Parts folder, Solid icon, Shell icon, or Beam icon and select Apply/Edit Material.

The Material dialog box opens.

  1. In the Material dialog box, right-click Custom Materials and select New Category. If needed, rename the New Category folder.

  2. Right-click the newly defined category and select New Material.

  3. Under Material Properties, select the desired options.

  4. In the material property table, click inside the Value cell of the material property that changes with temperature and select Temperature Dependent.

The Tables & Curves tab becomes active.

The material property that changes with temperature is selected by default in the Type menu.

  1. Set the Units of temperature and the material property.

  1. Type the temperature-property pairs in the table, or click File to read data from a *.dat text file with two columns of data.

To insert a new data row, double-click a cell in the Points column.

  1. To view the temperature-material property curve, click View.

  2. To save the material to a material database file (*.sldmat), click Save, give it a name, and click Save.

  3. Click OK.
