ON THE LENGTH-SCALE EFFECT IN THE FREE VIBRATIONS OF PERIODICALLY RIBBED ELASTIC PLATES
Journal Title: ELECTRONIC JOURNAL OF POLISH AGRICULTURAL UNIVERSITIES - Year 2010, Vol 13, Issue 4
Abstract
The plates reinforced by ribs are being considered in the paper. For such plates, by assuming a periodic distribution of the ribs in the plate, the average model was being constructed, consisting the plate dynamics equations, which are the linear differential ones with constant coefficients. For modeling the olerance not asym ptotic averaging technique were used. Consequently, in the modeling equations, a microstructure parameter remains (basic cell size). In the paper the free vibrations of the consideration plates were tested and the presence of scale effect was demonstrated
