This paper deals with elastic stress distributions and load carrying capacity of intact, broken and 5%-extended matrix crack proportional to broken ellipsoidal inhomogeneities. Finite element analysis has been carried out on intact, broken and crack extended to matrix broken ellipsoidal inhomogeneities in an infinite body under uniaxial tension. For the intact inhomogeneity, as well known as Eshelby's solution, the stress distribution is uniform in the inhomogeneity and non-uniform in the surrounding matrix. On the other hand, for the broken and crack extended to matrix broken inhomogeneity, the stress in the region near crack surface is considerably released and the stress distribution becomes more complex. Average stress in the inhomogeneity represents its load carrying capacity, and the difference of average stresses between the intact and broken inhomogeneities indicates the loss of load carrying capacity due to cracking damage. It is found that the broken ellipsoidal inhomogeneity with higher aspect ratio still maintains higher load carrying capacity.
