Szukana fraza: [Abstract = "The objects under consideration are thin linear\-elastic plates with periodic structure in planes parallel to the plate midplane, subjected to large \(of the order of plate thickness\) deflections. The main aim is to propose a mathematical model describing geometrically nonlinear problems of such plates, which is based on the tolerance averaging technique, cf. Woźniak et al. \[3\]. Results calculated for a special static problem by the tolerance model are compared with results obtained within the known tolerance linear model of thin plates."]
