Fur die nichtlinearen Biegeechwdngungen dunner rechteckiger oder kreisf ormiger Platten werden Ndherungslosungen angqeben, wobei verschiedene Falle von Randbedingungen betrachtet werden. Dabei wird der Einfhp groper Amplituden auf freie und erzwungene Schwingungen klargeatellt.Approximate solutions for the nonlinear bending vibrations of thin plates are presented for the cages of rectangular and circular plate8 subjected to various boundary conditions, and the effects of large amplitudes on both the free and forced vibration8 are clarified.

In the previous paper [1], the title problem is theoretically treated under eight different boundary conditions and numerical solutions are obtained for the deflection, edge shortening, and effective width of the square plate in edgewise compression. As a continuation of this work, the stress state in the buckled plate is investigated and numerical results for the square plate are given graphically. Further the formulas for the ultimate load of the square plate in each case are derived by using the maximum-shear theory for the beginning of yielding and comparison is made with the previous results and experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
