Abstract:The interfacial debonding of particulate-reinforced polymeric material is studied in this paper. Firstly, a nonlinear viscoelastic model is proposed to describe the constitutive relation of the polymeric matrix. Then the interfacial debonding of a particle embedded polymeric matrix material is analyzed, and the equation for solving the critical debonding time is derived. The expression of the debonding time under the condition of linear loading history is obtained from the equation. Finally, the numerical calculation is carried out, and the numerical results indicate that the debonding time is significantly influenced by the particle size, loading rate, interfacial adhesive energy and nonlinear viscosity parameter.
Keywords:nonlinear viscoelasticity  particulate-reinforced polymeric material  interfacial debonding  critical debonding time
