The Composite Materials Module
The Composite Materials Module is an optional add-on package for COMSOL Multiphysics® designed to assist you in modeling structural behavior that includes layered shells. The module is an add-on to the Structural Mechanics Module. The module is designed for researchers, engineers, teachers, and students who want to simulate the behavior of layered structures.
The Composite Materials Module provides the following extensions:
•
The Layered Shell physics interface
•
The Linear Elastic Material, Layered, the Hyperelastic Material, Layered, and the Piezoelectric Material, Layered material models in the Shell interface
•
The Linear Elastic Material, Layered material model in the Membrane interface
•
Multilayered functionality in the Thin Layer feature in the Solid Mechanics interface
•
The Thermal Stress, Layered Shell multiphysics interface
•
The Piezoelectricity, Layered Shell multiphysics interface (requires also the AC/DC or MEMS modules)
•
The Piezoresistivity, Layered Shell multiphysics interface (requires also the AC/DC or MEMS modules)
•
The Poroelasticity, Layered Shell multiphysics interface (requires also the Porous Media Flow module)
•
The Layered Shell–Structure Transition, Layered Shell–Structure Cladding, and Layered Shell–Shell Connection multiphysics couplings to connect the Layered Shell interface with other structural interfaces
•
Acoustic–Structure Boundary, Porous–Structure Boundary, Thermoviscous Acoustic–Structure Boundary, and Aeroacoustic–Structure Boundary multiphysics couplings to connect the Layered Shell interface with acoustics interfaces (requires also the Acoustics module).
•
Fluid–Structure Interaction multiphysics coupling to connect the Layered Shell interface with fluid interfaces (requires also the CFD module).
•
Lumped–Structure Connection to connect the Layered Shell interface with the Lumped Mechanical Systems interface (requires also the Multibody Dynamics module).
•
The Layered Material node under global materials, in which you specify the layup of a stacked material. The Layered Material Stack node under materials.
The Linear Elastic Material, Layered in the Shell and Membrane interfaces is also available with the Structural Mechanics Module. However, its usage is then restricted to a single layer material. In that context, is mainly intended for modeling using nonlinear material models in the Shell interface and multiphysics couplings in the Shell and Membrane interfaces.
The Hyperelastic Material, Layered in the Shell interface is available with Nonlinear Materials Module. The Piezoelectric Material, Layered in the Shell interface is available with AC/DC or MEMS modules.
