Combining the contact elements into the two-scale homogenization method, the effective mechanical properties of nano-composites with a debonding interface are analyzed. A periodic microscopic representative volume element (RVE) is modeled by using a four-phase composite composed of matrix, nano-tube, bonded, and debonding interfaces. The initial stress and coulomb's friction are considered within debonding interface, which is applied to transfer the shear stress produced by the relative slip between nano-tube and matrix, and a simple elastic-plastic constitutive model is established to study the effective mechanical properties of nano-composites. The predicted results show a strong non-linear dependence of the effective mechanical properties on the elastic modulus, volume fraction, debonding length and the ratio of length with thickness of interface.
