Abstract
It is shown that for corrugated, in particular multilayer, plates, the tree-dimensional cell-averaging problem can be reduced to the two-dimensional problem on the cross section of the plate periodicity cell. This significantly increases the accuracy of numerical calculation of the effective stiffness of corrugated plates. Numerical calculations of the stiffness of a plate with sinusoidal corrugation were performed, and the results were compared with available data.
