摘要：

Combined with the uniaxial compression creep test and viscoelastic material modeling theory of generalized Maxwell, the coefficients of relaxation modulus Prony series of absorption and floating viscoelastic filler material were obtianed. The creep charateristic experiment of viscoelastic composite sandwich structure under water was carried out, and the results were compared with the simulation research. The results show that at the long-term creep stage of composite materials sandwich structure, the core material has a dominant presence compare with composite material; with the increase of time, the creep and relaxation phenomena exhibited by viscoelastic properties of the surface composite matrix appear alternately, the surface strain fluctuates; on long-term creep deformation of composite sandwich structure, the core material contributes about 60%. © 2016, Editorial Board of Journal of Ship Mechanics.
