Abstract

In the classical work of 1957, Eshelby proposed a solution to the three dimensional elasticity problem of evaluating the stress distribution when inhomogeneous inclusions are embedded in an infinite elastic body. Later, his approach was applied to the nonlinear micromechanics problem of determining thermal residual stresses for composites. Eshelby's solution, valid only for an isolated unidirectional fiber, is extended in this paper to include the effect of the interaction of neighboring fibers in a regularly packed array. The stress field at any given material point is obtained as a superposition of the field due to the disturbance of all the fibers in the composite. The theoretical results are compared with finite element solutions, and they match very well.
