Аннотация:Abstract—Using the previously obtained equations of motion of thin couple stress elastic shellsof constant thickness with an arbitrary smooth median surface, the corresponding equations foran isotropic couple stress c ircular cylindrical shell in the forces and displacements (kinematicparameters) are constructed, while natural kinematic and static boundary conditions are given atthe end sections. As a result, twelve equations of motion and corresponding physical relations areobtained.
