Abstract
A fiber-reinforced elastic composite subjected to residual radial (compressive) and axial stresses, induced by mismatch strains between the fiber and the matrix, is considered. For an unbonded or a weak interface, sliding at the fiber-matrix interface can occur due to resiidual stresses. The sliding length and the stress distribution in the composite are analyzed in the present study. The results show that the sliding length is limited by he interfacial friction. The fiber can pop out of or sink beneath the surface of the composite depending mainly on the mismatch strain in the axial direction. However, the sliding phenomena are modified by the mismatch strain in the radial direction because of Poisson's effect. ? 1991.
