Abstract : The stress fields around multiple inclusions have been calculated by using the finite-element method, and observed by the photoelastic technique. Discontinuous fibrous composites are simulated by glass-epoxy specimens. The distributions of the fiber stress and the interfacial shearing stress are found to differ significantly from those calculated by the shear lag analysis. The perturbation effect of fiber stress, the concept of typical region, and the boundary conditions around the fibers are discussed. (Author)
