Abstract
In this paper, the stress distribution around the spherical particle in polymeric based composite materials was analyzed using axisymmetric finite-element method. The effect of varying Young's modulus and volume fraction of second-phase particle was examined. Predicted values of the modulus of particle-filled composite were given as function of the volume fraction of filler. Based upon these calculated results, various damage mechanisms relevant to the stress conditions in loaded materials were discussed. It is shown that the numerical predictions are in qualitative agreement with the microscopical observations.
