Bi-axial buckling behavior of composite rectangular plates

Buckling behavior of composite plates subjected to bi-axial loading was experimentally determined and numerically analyzed. Modified rectangular specimens were introduced to overcome one of the experimental obstacles in which the loading grips interfere with each other's motion at each corner during the continuous bi-axial compression process. To determine the effects of modifications of the plate specimen, finite element analysis was performed in which the large deflection but small strain conditions were considered. In this paper, three different types of results which were determined from theoretical, numerical and experimental approaches are presented.
