On Buckling of Plates under Compression and Hydraulic Pressure

Abstract

In this paper, the behavior of a plate under increasing compression and constant hydraulic pressure is investigated by means of the energy method. Numerical calculations are performed for a case of the aspect ratio α=2, and it is shown that there are three kinds of typical deformation patterns for such a plate according to the magnitude of hydraulic pressure. And buckling load is also dircussed in such practical cases that there are disturbances and initial distortions.
