This article discusses a method for calculating the dynamic characteristics of thin-walled viscoelastic composite pipes made by continuous winding under the influence of internal hydrodynamic pressures. The solution is based on an approximate energy method based on the instant theory of shells and the second-order Lagrange equation. Initial technological irregularities are taken into account. The pipe is considered a multilayer viscoelastic toroidal shell with variable reinforcement parameters,doi:10.24874/jsscm.2019.13.02.08 fatcat:m6en34zmnnenvjtssg2swrv5cm
