Micromechanical Model of a Particulate Composite
Application ID: 107901
In this example, the homogenized elastic and viscoelastic properties of a particulate composite are computed based on the individual properties of elastic particles embedded in a viscoelastic matrix.
Periodic boundary conditions are applied to a unit cell of the particulate composite using the Cell Periodicity feature in the Structural Mechanics Module.
The transient viscoelastic response of the composite is used to determine the homogenized material parameters using curve fitting optimization.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® and
- either the MEMS Module, or Structural Mechanics Module and
- either the Battery Design Module, Chemical Reaction Engineering Module, Nonlinear Structural Materials Module, Optimization Module, or Polymer Flow Module
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
