About Character of Natural Vibrations of Orthotropic Shells in the Presence of Viscous Resistance

Basing on the equations of three-dimensional problem of elasticity theory, asymptotic solutions of non-classical boundary value problems of natural vibrations of orthotropic shells in the presence of viscous internal resistance are obtained, when the top front surface of the shell is given with two...
