Rigidity of three-layer plate with discrete parameters

Abstract The method of calculation of three-layer panels with cuts and holes, enabling one to take into account the effect of different peculiarities on the distribution of strains and moments with good accuracy, is presented. Tasks for the estimation of three-layer plates with the sections and apertures practical work are solved in the conditions of various options of edges fixation and different types of loads. The estimation method on rigidity of three-layer plates with the sections and apertures has been drawn.
