Entities

If the geometry has no T’s, a single laminate entity should be used per physical part. If the geometry is complex, for example, contains T’s and an I-beam, sublaminates should be used to define each portion of the total part and a single interface laminate should be used to bring sublaminates together.

For more information on laminate entities, see Laminate Entities.

Ply entities in HyperMesh should be treated as analogous to a layer of composite material on a physical part. They define material, thickness, orientation and shape.

For more information on ply entities, see Ply Entities.

Sequences can be used to rapidly generate plies within a laminate and for organizational purposes within a laminate. A main sequence is defined with some (typically small) list of layers which is common in a model (for example, [-45/0/45/90] of all the same ply product). This sequence can then be dragged into a laminate, exactly like a ply, to create an instance sequence. On the instance sequence, a number of repeats can be specified as well as a ply shape. Any changes to the main sequence will propagate to the instances. For more information on ply entities, see Sequences.

The properties could be isotropic, orthotropic or anisotropic. Specific solver card images will depend on the user profile, physical material properties and the scale of homogenization for the modeled material.

In typical composite models defined in HyperMesh, the material is referenced by ply entities (ply based shell models), layers in property entities (zone based shell models/layered solid models) or in property entities (solid models).

For more information on material entities, see Material Entities.

Set entities are used as a method to define ply shape for ply-based models. Sets contain the list of elements that make up the shape of the ply.
