Dynamic problems for elliptical cylindrical shells under distributed nonstationary loads are formulated. The equation of vibrations is derived from the Hamilton–Ostrogradsky variational principle based on the refined Tymoshenko-type theory of orthotropic shells. A numerical algorithm for solving these problems is developed. It allows obtaining numerical results with a given accuracy. The effect of cross-section ellipticity on the stress–strain state of a closed cylindrical shell with clamped ends under uniformly distributed internal impulsive pressure is studied.
