A theoretical model is developed to predict debond onset in spherical-particle-reinforced composites subjected to uniaxial tension. The coupled stress and incremental energy criterion of the finite fracture mechanics is applied employing an axisymmetric boundary element method code, which is highly accurate in the analysis of interface cracks in presence of contact. The model enables to predict the value of the critical remote load and the spherical angle of the debond after the onset as a function of the particle, matrix and interface properties and particle size. Results predicted are compared with experimental observations found in the literature.
