Abstract

The postbuckling behavior of square flexible orthotropic and isotropic plates weakened by a square opening is investigated. The load is uniformly distributed along two opposite hinged edges, the other two unloaded edges being free. The solution is obtained in finite differences by successive approximations. Calculations have been made for 1:1, 5:1, and 10:1 SVAM and steel using a Minsk-22 computer.
