Abstract: Statements are given, solution methods are developed, and numerical results are obtained for new problems of stationary deformation of infinitely long viscoelastic cylindrical shells on a deformable base when a non-axisymmetric normal pressure wave moves along the shell axis with up to resonant velocity. The solution methods are based on the joint application of the integral Fourier transform (or the method of fundamental solutions) along the axial coordinate and the expansion of all given and desired values in Fourier series along the angular coordinate. An efficient algorithm for the joint calculation of integrals and Fourier series has been developed and implemented on a computer. An estimate of the mixed shell is given depending on the velocity of the pressure waves and the viscosity of the materials.

Key words: pressure waves, cylindrical shell, viscoelasticity, resonant velocity, Fourier transform, deformable foundation.
