Aiming at the micro-damage nucleation mechanism of micro-hole-filled polymer composites due to the debonding of the phase interface, micro-damage nucleation mechanism of the micro-holes was established. The dynamic analysis of the representative volume elements of the material was carried out. Laplace transformation of the constitutive relation of the viscoelastic matrix Hankel transform was introduced to obtain the analytic solution of the stress variation of phase interface under the symmetrical dynamic load. Based on this, the influence of inertial and viscous effects on the interface debonding was analyzed.
