“…The main dimensions of the perforated plate were length (a), breadth (b), thickness (t), opening in the plate length direction (L), opening in the plate breadth direction (D), axial displacement (U), and lateral deflection (w). To investigate the lateral deflection characteristics of the perforated plates, we considered three variables-opening size (D/L), thickness (t), and aspect ratio (a/b)-on the basis of previous studies and actual shipment data [3,[11][12][13]. From the previous reference data, the dimensions of the plates used in shipbuilding industries are in the following range: aspect ratio (1.00-6.55), slenderness ratio (1.42-3.83), breadth (800-975 mm), thickness (10-22 mm), opening size (400 mm × 600 mm, 500 mm × 700 mm, 600 mm × 800 mm), and opening ratio (0.44-0.83).…”

“…However, it is inevitable to investigate the structural behavior and strength characteristics of the perforated plate because it is known that opening leads to a significant reduction in the ultimate strength. Consequently, several studies on perforated plates have been conducted through experimental and finite element analysis to predict the buckling and ultimate strength [1][2][3][4]. The numerical and buckling analyses of thin steel plates with centered perforations through various design method is reported.…”

This study aimed to investigate the behavioral characteristics of the lateral deflection of a simply supported perforated steel plate subjected to axial compression. Investigating the lateral deflection of the perforated plate is of great significance because the buckling limit of structural members can be predicted not only by strength but also by displacement (or deflection). For this purpose, we conducted buckling experiments by considering various variables of the perforated plate, such as opening size, thickness, and aspect ratio. In addition, a series of elastoplastic large deflection analyses were performed using the commercial finite element analysis program, and the calculated results were compared along with the experimental results. Finally, practical curves, which can predict lateral deflection with an increase in axial displacement, and the occurrence point of ultimate strength are reported in this study. The results showed that there was a distinct difference in the behavior of lateral deflection between perforated plates with different opening ratios. The local buckling occurred mainly around the opening and was more dominant with an increase in the opening ratio. In addition, the ultimate strength of the perforated plate was determined at the end of the local buckling phase.
