Homogenized Material Properties of Periodic Microstructures

Application ID: 109241

Periodic microstructures are frequently found in composite materials, metallic foams, and sandwich structures. They can be described by a unit cell repeated along the three Cartesian directions.

This app computes homogenized material properties of various periodic microstructures and makes them available in an MPH-file or an XML-file that can subsequently be imported into a COMSOL Multiphysics session.

Ten different microstructures represented by unit cells are available. The dimensions are modifiable by the user, as well as the properties of the constituent materials. The app calculates the homogenized density, elasticity matrix, coefficient of thermal expansion, heat capacity, and thermal conductivity which can then be used in macroscopic analyses.

This application example illustrates applications of this type that would nominally be built using the following products:
