The theory of plates and shells is the most important application of the theory of elasticity. Rectangular slabs of average thickness are quite widely in construction, engineering and other fields of modern technology. Calculation of such structures cannot be conducted on the basis of the classical theory of bending of thin plates. In order to obtain a reliable picture of stress-strain state of a plate with average thickness, it is necessary to use different versions of improved theories. The aim of this work is the use generalized equations of the finite difference method (FDM) to calculate the dynamic loads of the plates average with thickness basing on the Reissner theory. On the basis of the developed algorithms computer programs have been worked out for calculating the dynamic load of bending plates of average thickness. The algorithm of calculating the dynamic load of bending plates of average thickness according to generalized equations of FDM can be recommended for practical use in frames of studying process.
