The interfacial debonding considering cohesive force in a particulate-reinforced polymeric composite is investigated in the present study. The constitutive relations of polymeric matrix and inclusions are both approximately described by linear elastic models. It is assumed that the interfacial debonding between inclusions and matrix is dominantly induced by the hydrostatic component of remote stresses. The interfacial debonding of an inclusion embedded in an infinite space matrix is analyzed. It is found that the size of inclusion will significantly affect the debonding strength, especially when it is in nano-scale. The relation between particle Poisson's ratio and debonding strength is approximately linear.
