The Materials form will appear when the Materials toggle, located on the Patran main form, is chosen. The selection made on this form will determine which materials form will be presented, and ultimately, the material to be created.
The following pages give an introduction to the Materials forms, followed by definitions of all the materials properties supported by the Patran ANSYS Application Preference.
References to externally defined materials (i.e., materials whose property values are not defined in Patran) will result in a special comment and the creation of either the ANSYS ISOTROPIC or ORTHOTROPIC option with zero values for all properties.

Composite
The Composite forms are used to create new materials by combining existing materials. All of the composite materials, with the exception of the laminated composites, can be assigned to elements, as any homogeneous material, through the element property forms. For the laminated composites, the section thickness is entered indirectly through the definition of the stack. The Homogeneous option for shells, plates and beam, must be changed to Laminate to avoid reentry of this information.
Laminated
This form appears when Composite is the selected Object and Laminate is the selected Method on the Materials form. Use this form to create the ANSYS real constant cards associated with the composite elements. This may be used with SHELL91, SHELL99, or SOLID46 elements only. Layers are numbered from the bottom of the element.
