Creating Materials
When using MSC.Laminate Modeler there are three levels of material generation.
1. Patran homogeneous materials should be generated using standard Patran functionality. These contain mechanical, thermal or physical data which can be manually input or imported Using Patran Materials (p. 10) in the Patran Materials Enterprise.
1. MSC.Laminate Modeler ply materials. These ply materials have thickness and manufacturing data in addition to a reference to an appropriate material in the Patran database. These ply materials are used to create plies in the MSC.Laminate Modeler module.
1. Patran laminate materials which are built up from Patran homogeneous materials by the MSC.Laminate Modeler software on the basis of the user-specified layup sequence, offsets and tolerances.
Patran Homogeneous Material Definition
The main description of the materials is done using the standard Patran methods of definition. The Materials form can be used to generate the required materials. Methods available include user input, external definition and Patran Materials.
MSC.Laminate Modeler Ply Material Definition
The homogeneous materials created, within the standard Patran form, are referenced within the MSC.Laminate Modeler Create LM_Material Add form to generate ply materials with extended property sets which include thickness and manufacturing data, such as the maximum strain allowable during draping.
Material Application Types
Ply materials are categorized by the way in which they are applied to a selected surface. They reference particular types of Patran homogeneous materials.
• Painted
Isotropic materials are supported for Painting.
• Projected
2D/3D orthotropic and anisotropic materials are supported for Projecting.
• Scissor Draped
2D/3D orthotropic and anisotropic materials are supported for Scissor Draping.
• Slide Draped
2D/3D orthotropic and anisotropic materials are supported for Slide Draping.
 
Additional Ply Material Parameters
• Thickness
• The thickness of a single ply of the material before it is sheared.
• Maximum Strain
The allowable strain value before the material “locks” (i.e., the material can no longer conform to the surface by shearing). This is measured in degrees.
• Initial Warp/Weft Angle
This value describes the original undeformed angle between warp and weft yarns in a fabric. This value can be overridden on the Create LM_Ply Add, Additional Parameters form. This allows deformation of the fabric before it is placed on the model, which may achieve better draping. This angle is measured in degrees.
