17.6.4.9. Plastic Heating

The Plastic Heating boundary condition enables the thermoplastic effect, that manifests itself as an increase in temperature, during plastic deformation due to the conversion of some of the plastic work into heat.

This page includes the following sections:

Applying a Plastic Heating Boundary Condition

To apply a Plastic Heating:

  1. On the Environment Context tab, select Plastic Heating from the Conditions drop-down menu of the Structural group. Alternatively, right-click the Environment object or within the Geometry window and select Insert>Plastic Heating.

  2. Define the Scoping Method as either Geometry Selection or Named Selection and then specify the geometry.

  3. Specify the Plastic Work Fraction.

Details Pane Properties

The selections available in the Details pane are described below.

CategoryProperty/Options/Description
Scope

Scoping Method: Options include:

  • Geometry Selection: Default setting, indicating that the boundary condition is applied to a geometry or geometries, which are chosen using a graphical selection tool.

    • Geometry: Visible when the Scoping Method is set to Geometry Selection. Displays the type of geometry (Body, Face, etc.) and the number of geometric entities (for example: 1 Body, 2 Edges) to which the boundary has been applied using the selection tools.

  • Named Selection: Indicates that the geometry selection is defined by a Named Selection.

    • Named Selection: Visible when the Scoping Method is set to Named Selection. This field provides a drop-down list of available user-defined Named Selections.

Definition

Plastic Work Fraction: This value defines the fraction of work that is converted to heat.

Suppressed: Include (No - default) or exclude (Yes) the boundary condition.
