Abstract: Based on Boltzmann’s viscoelastic theory, the mathematical model of a free-standing viscoelastic ring subjected to uniform pressure is established by applying assumed modes method, Galerkin method and numerical method. It is found that, the free-standing viscoelastic ringing has both a stantaneous critic load and a durable critic load under uniform pressure. The influence of structure size and parameters of the material are discussed, The evolutionary trend of the system is also investigated.
