Three-point correlation bounds on the effective bulk modulus of isotropic multicomponent materials

Pham Duc Chinh, Vu Lam Dong

Abstract


Three-point correlation bounds based on minimum energy principles are constructed to give estimates on the effective elastic bulk modulus of disordered multi-component materials. The constructed trial fields are extensions of Hashin-Shtrikman polarization ones used in our previous approach and lead to tighter bounds. Some examples of applications are presented.

Keywords


Isotropic multicomponent material; effective elastic moduli; three-point correlation parameters
