DETERMINATION OF THE CONSTITUTIVE COEFFICIENTS FOR A MIXTURE OF TWO SOLIDS.
CALIFORNIA UNIV BERKELEY DIV OF APPLIED MECHANICS
Pagination or Media Count:
Using a theory of mixtures allowing different temperatures for each constituent, we first discuss non-linear constitutive equations for a mixture of two elastic solids. Then, upon specialization, we determine relations between certain of the material constants related to each constituent and the corresponding constants related to the mixture. We linearize the constitutive equations by assuming that all displacements from the undeformed state, and all subsequent temperature changes, are small and we further show how to evaluate the constants appearing in the linearized constitutive equations, under certain assumptions which are shown to be thermodynamically consistent.
