Abstract : The stress field surrounding a high-modulus, rectangular inclusion embedded in a low modulus matrix was thoroughly studied. Increasing inclusion/matrix modular ratio results in an increased strengthening effect in the matrix over much of the inclusion length, and an increase in both principal and shear stresses at the inclusion end. For a particular matrix material, there is an optimum inclusion/matrix modular ratio at which a relative maximum strengthening effect is obtained and the model does not fail by either shear debonding or yielding at the inclusion end, resulting in shear debonding.
