| Abstract: | The present paper is devoted to the study of expansional behaviours of acomposite reinforced by spherically isotropic particles. An exact relation is derived between the effective expansion coefficient and bulk modulus of the composite by using the concept of uniform fields in the matrix which is proposedhere. Through obtaining the Paul-type bounds of the bulk modulus by using theextreme principle of energy, bounds of the effective expansion coefficient arealso derived. |
