Non-stationary dynamics of Timoshenko circular plate of variable thickness

The comparison of calculation results obtained with the solving of non-stationary dynamic problem for Timoshenko circular plate of piece-wise variable thickness (consisted of the Timoshenko circular plates set of variable thickness set) in series by eigenforms and for Timoshenko plate with thickness varying continuously by the radius of plate using the numerical solution of equilibrium equations (of motion) obtained by variational principle of Hamilton–Ostrogradskii is presented.
