Composite Materials Modelling in COMSOL Multiphysics® Webinar is Now Available on Demand

Wind Turbine Blade

COMSOL held a webinar on Modelling Composite Materials, where Robbie Balcombe, Technical Director at COMSOL Ltd, demonstrated how to model layered composite structures in COMSOL Multiphysics®.

The webinar is now available on demand here: http://uk.comsol.com/c/8a5x

Common examples of composite materials include fibre-reinforced plastic, laminated plates, and sandwich panels, all of which are widely used in the manufacturing of aircraft and spacecraft components, wind turbine blades, and other structures.

In this webinar, two approaches were discussed to accurately model composite shells: layerwise theory and equivalent single layer theory. In addition to standard structural analyses (such as stationary, eigenfrequency, transient, and frequency domain), the presentation went over micromechanical, first-ply failure, and linear buckling analyses. The presenter showed how to include various physical phenomena, such as heat transfer and fluid flow, in a composite laminate model. A demo in the COMSOL Multiphysics® software showed simulation results for the through-thickness and ply-wise stress distribution in the composite laminate.

COMSOL released the new Composite Materials Module last October with its COMSOL Multiphysics® Version 5.4. “The Composite Materials Module delivers modelling tools for users working with layered materials”, said Pawan Soami, Technical Product Manager at COMSOL. “Composite laminated structures could have more than a hundred layers and setting up such a simulation is cumbersome without dedicated tools. We now offer such tools”, continues Soami.

By combining the Composite Materials Module with new functionality for layered shells available in the Heat Transfer Module and the AC/DC Module, users can perform multiphysics analysis such as Joule heating with thermal expansion. “The ability to couple structural mechanics analysis in layered shells with heat transfer and electromagnetics, provides users with unique multiphysics modelling capabilities”, says Nicolas Huc, Technical Product Manager at COMSOL. An important application of multiphysics analysis in laminated materials is managing the impact of lightning strikes on wings and wind turbine blades within aerospace and wind power industries.
