Damage Material Properties

When a damage analysis is chosen, the material properties include all the Orthotropic Material Properties and the following properties. (See the paragraph Defining the Damage Analysis Type on the page Setting Up and Performing the Analysis: Nonlinear: Element Types and Parameters:2D Elements for setting the damage analysis.)

Tip: Use the Material Axis Direction on the General tab of the Element Definition dialog to set up the orientation of the material. See the paragraph Controlling the Orientation of 2D Elements on the page Setting Up and Performing the Analysis: Nonlinear: Element Types and Parameters: 2D Elements for details.

Some input is not necessary depending on the damage analysis selected.

Composite Strength:

The Composite Strength section gives the input for the material strengths for determining the damage initiation. Axis 1 corresponds to the material axis 1, and the fibers are parallel to this axis. Axis 2 is perpendicular to the fibers. All material properties are for the combined fiber and matrix composite.

Energy Dissipation:

The Energy Dissipation section gives the input for the material energy dissipation rate to evaluate the damage growth.

Refer to the following page, Damage Theoretical Description, for additional clarification and equations in which the material properties are used.
