Thermoplastics Material dialog-Mechanical Properties tab

This dialog is used to view the properties of the selected thermoplastics material.

The Mechanical Properties tab of the Thermoplastic material dialog is used to specify the mechanical properties of the thermoplastics material.

Note: If a property name is shown in red, it indicates that the property has not been tested for this specific material. However, material data from the testing of a comparable generic grade was found to be suitable and has been assigned to this material.

Mechanical properties data	These inputs are used to specify the mechanical properties of the material (matrix + fibers/filler in the case of composite material) according to the five standard coefficients used to describe a viscoelastic material. A viscoelastic model must be used when stress relaxation data is required as a function of time and temperature. For example, a part under load and subject to a heating cycle can deform as a stress relaxation. This model will account for variation in properties in the flow direction and transverse to the direction of flow.
Viscoelastic properties data	If you are using a material that has viscoelastic properties data, select Unified viscoelastic from the drop down list, then select Edit Unified viscoelastic properties to display the Unified viscoelastic properties dialog to edit the viscoelastic properties. The default setting is Do not use.
Transversely isotropic coefficient of thermal expansion (CTE) data	These inputs are used to specify the thermal expansion properties of the material (matrix + fibers/filler in the case of composite material). The Transversely Isotropic CTE coefficients combine with the Mechanical Data model to account for variation in properties in the flow direction and transverse to the direction of flow. Following are the Transversely Isotropic CTE coefficients: Alpha 1 The thermal expansion coefficient in the flow direction. Alpha 2 The thermal expansion coefficient in the transverse direction.
View/edit test information	Click this button to view the source of this material data, the date that the data was last modified, the date of testing and the test method that was used for the data. For more information about Autodesk Simulation Moldflow materials data and material testing methods, see Material testing and data fitting.
Use matrix properties	If you are using a material that has isotropic or anisotropic matrix data, select Use 7 matrix properties from the drop down list, then select Edit matrix properties to display the Matrix properties dialog to edit the matrix properties. The default setting is Do not use matrix properties. When you use matrix properties with materials that have anisotropic matrix data, the Mori-Tanaka micro-mechanics model will be used by default. If you select Do not use matrix properties, or if you select Use 7 matrix properties with materials that have isotropic matrix data, the Tandon-Weng micro-mechanics model will be used by default. Use 6 matrix properties (Obsolete) is included for backward compatibility with old study files. Note: Using the Mori-Tanaka micro-mechanics model with anisotropic LCP materials will improve the accuracy of analysis results.
