    Abstract

    Residual stresses in and around short fibers in metal matrix composites due to temperature change are evaluated. An analytical result for the residual stress in the fiber is obtained by use of Somigliana dislocations at the matrix-fiber interface. These dislocations are introduced to accommodate the misfit of the thermal expansion difference between fibers and the matrix. These dislocations are responsible for the residual stresses after the composite material is cooled down to room temperature.
