Approximate methods for numerical evaluation of the elastic moduli of composite and microheterogeneous materials

Article

Approximate methods for calculating the effective elastic moduli of microheterogeneous materials, including multiphase ones, are considered. These methods are based on the analogy between the electrostatic field in dielectrics and the field of elastic stresses and strains in solids. Formulas are derived for the quantitative evaluation, with accuracy sufficient for materials science practices, of the effective elastic moduli of composites with different structures as a function of the elastic moduli, morphology, and volume fraction of the phases. The method is validated by calculating the elastic characteristics of bodies with plane slit-like defects, including powder compacts.
