Calculation of the effective stiffnesses of corrugated plates by solving the problem on the plate cross-section

Resumo

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