Create Composite Material Plug-in

Follow the steps below to assign the AS4-PEEK material to part Composite_Plate.

1. Select Plug-ins > Autodesk > Create Composite Material from the main toolbar.
2. From the Material Library list, select the material AS4-PEEK.
   Note: The unit system dependent Engineering Constants specific to this material are listed in the dialog box for you to review.
3. Since this model uses meters and Newtons as base units, select N/m/K from the Select Model Units list. There are 4 unit systems to choose from. The default unit system is N/m/K.
4. Select 1 as the fiber direction.

   2 can also be used as the fiber direction, but it would require a different composite layup orientation than the 1 direction. As a general rule, it is recommended that 1 be used as the fiber direction to maintain consistency from model to model. On occasion, however, it will not be possible to create an orientation in Abaqus that allows for the 1 direction to be the fiber direction due to the combination of complex model geometry and section orientation limitations. In such cases, it may be necessary to use the 2 direction as the fiber direction.

5. In the Damage Evolution menu, select Instantaneous Degradation. Only discrete damage evolution is supported for fatigue analyses. For Instantaneous Degradation damage evolution, the stiffnesses of the elements are reduced after failure has been predicted by the failure criterion.
6. The plug-in should appear as shown below.
7. Click OK.

After completing steps 1-7, a user material is created in the Materials container in the Material Tree. This material is used to define the composite layup for the plate.
