Selecting the Mori-Tanaka micro-mechanics model

The Mori-Tanaka micro-mechanics model can be used to calculate the mechanical properties of fiber-filled composites with anisotropic matrix material properties. This model is selected by default if your material contains anisotropic matrix data.

Tip: You can choose to use the Mori-Tanaka micro-mechanics model instead of the Tandon-Weng model when your material has isotropic matrix data, or when it has composite properties, by changing the solver parameter for the micro-mechanics model from Automatic to Mori-Tanaka.

Note: The Mori-Tanaka micro-mechanics model may not improve calculations when materials with isotropic matrix material properties are used.

1. Click (Home tab > Molding Process Setup panel > Process Settings).
2. If necessary, click Next until the Fill+Pack Settings page of the Process Settings Wizard appears.
3. Ensure the Fiber orientation analysis if fiber material check box is selected.
4. Click Fiber parameters.
5. Click Composite property calculation options.
6. From the Micro-mechanics model list, select Mori-Tanaka.
7. Click OK in the Composite property calculation options dialog, and then click OK in the Fiber Orientation Solver Parameters dialog to return to the Fill+Pack Settings page of the Process Settings Wizard.
8. Click Next until you reach the end of the Process Settings Wizard, and then click Finish.

The Mori-Tanaka model is used when running a Warp or Shrink analysis.
