EFFECTIVE ELASTIC MODULI OF INHOMOGENEOUS SOLIDS BY EMBEDDED CELL MODEL
<正> An embedded cell model is presented to obtain the effective elasticmoduli for three-dimensional two-phase composites which is an exact analytic formulawithout any simplified approximation and can be expressed in an explicit form. Forthe different cells such as spherical inclusions and cracks surrounded by sphere andoblate ellipsoidal matrix, the effective elastic moduli are evaluated and the resultsare compared with those from various micromechanics models. These results showthat the present model is direct, simple and efficient to deal with three-dimensionaltwo-phase composites.
