Acoustical Response of Particulate-Loaded Viscoelastic Composites
In a recent study we proposed a general thermomechanical theory describing the behavior of multiphase mixtures which includes, for example, the response of a viscoelastic matrix with particulate inclusions.1 Although the theory is a continuum theory, it considers the discrete nature of the phases of the mixture by associating with each material point a more complex structure to represent the interactions between phases. In particular the volume fraction of each phase is considered as an independent kinematic variable. This leads to additional force balance equations which relate to the interfacial force system and serve to describe the microstructural behavior of the mixture.
