This work concerns the application of integral transformations U> (fie analytical solution of non-stationary state of stress in a thin homogenous isotropic viscoelastic plate. Owing to the axial symmetry of applied loading and the infinite geometry of the plate, the problem is solved as an axisymmetric one 'md the cylindrical spatial coordinates are used. The theory of thin plates with -1cral corrections is used during the derivation of motion eąuations. After that, the system of two dependent partial integrodifferential equations of the second oidcr is solved using the Laplace and Hankel transformation in the time and spatial domain, respectively. The transforms of unknown functions representing deflection and deflection angle are obtained.
