Composite Failure Tool (Group)

Provides result data that corresponds to that of the failure definition in Ansys Composite PrepPost (ACP). Refer to the Ansys Composite PrepPost User's Guide for the complete workflow associated with composite analyses as well as the Composite Failure Tool section of the Ansys Mechanical Help for a description of the use of this tool.

Composite Failure Tool Result Objects

The result objects Inverse Reserve Factor, Safety Factor, and Safety Margin are only used with the Composite Failure Tool. The Details pane properties for these objects include the following.

CategoryProperties/Options/Descriptions

Scope

Scoping Method: Geometry Selection and Named Selection.

Geometry: Appears if Scoping Method = Geometry. Use selection filters to pick geometry, click in the Geometry field, then click Apply.

Named Selection: Appears if Scoping Method = Named Selection. Specify named selection.

Sub Scope By: Options include:

  • Entire Section (default)

  • Ply: If selected, a Ply property also displays that requires you to select a target ply from the Modeling Ply object in the tree. The result calculation uses the intersection of the specified Ply and the Geometry property scoping.

Definition

Type: Result type indication, can be changed within the same result category. Options include:

Show Critical Failure Mode

Show Critical Layer

Threshold for Text Visualization: Value property.

Show On Reference Surface: Use this property when you import a model from Ansys Composite PrepPost (ACP) that includes a specified Reference Surface. Options include No (default) and Yes. When set to No, the solid mesh displays the worst failure and mode per solid element. When set to Yes, the result displays the worst failure, per solid stack, on the shell mesh of the specified Reference Surface only.

By: Options include Time and Result Set. They visualize the intermediate results by a time value or a result set.

Display Time: Appears if By is set to Time.

Set Number: Appears if By is set to Result Set.

Calculate Time History: Currently, time history is not supported.

Suppressed: Suppresses the object if set to Yes.

Integration Point Results

Display Option: Read-only indication of either Ply Maximum or Elemental Maximum.

Results - Read-only status indication of result object.
