A Constitutive Relation of Foam Materials
Authors:Liu  Zhanfang
Abstract:A constitutive model for foam materials is developed based on the Mixture Theories extended by the concept of volume fractions. Within the framework of the axiom of rational thermodynamics, the thermodynamical restrictions on the constitutive relations are investigated and the constitutive equations are formulated for the solid gas two phase foam materials.
Keywords:foam materials  porous medium  constitutive relation  rational thermodynamics
