Laminate Composites > Defining plies and a stacking sequence

Ply properties

You can define the following properties for a ply:

  • Ply ID

  • Material

  • Thickness

  • Orientation angle

  • Color

  • Description

  • Ply failure theory

  • Interlaminar failure theory

You must always define a material and a thickness. The software automatically assign a ply ID, but you can overwrite it.

When you create plies for a Solid Laminate physical property, you can also define for each ply:

  • Ply failure theory

  • Interlaminar failure theory

  • Layered or homogeneous solid property

Material

Valid materials are:

  • Any isotropic or orthotropic material defined in the material library or defined as a new material.

  • Any ply material defined in the Ply Material dialog box.

Ply orientation

The ply orientation angle defines how each ply is oriented when it is stacked in a layup. When the angle is 0, the material properties of the ply align with the material direction that you define on the element or mesh. In this case, the ply coordinate system is the same as the material coordinate system.
