Use the Simulation Composite Analysis plug-in interface to choose from a variety of material and analysis options.
The material and analysis options include the following:
Using these options, you can tailor your analysis to the requirements of the problem. For a detailed discussion of the options available, refer to the Simulation Composite Analysis User's Guide.
In the following steps, a user-material is created for the plate, and progressive failure analysis is requested using the Simulation Composite Analysis GUI.
The unit dependent Engineering Constants specific to this material are listed in the plug-in for you to review. Note the ANSYS Material ID (matID) corresponding to this material is also shown in the dialog box. This value may vary from computer to computer. It is useful to know the Material ID when working with input files since ANSYS uses the matID to identify Simulation Composite Analysis materials.
There are 4 unit systems to choose from. The default unit system is N/m/K.
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 ANSYS that allows for the 1 direction to be the fiber direction due to the combination of complex model geometry and orientation limitations. In such cases, it may be necessary to use the 2 direction as the fiber direction.
These values specify the ratio of damaged to undamaged material properties for the material. For example, a value of 0.01 for the Fiber Post-Failure Stiffness means that when an integration point undergoes a fiber failure event, the material properties at that integration point will degrade to 1% of the undamaged properties.
