A Novel Evaluate the Ultimate Strength of Plate Having Cutout Under In-Plane Compression

In this study, investigating the effect of different sizes, cut out shapes and different shapes of the structural to the ultimate strength of steel panels. The nonlinear finite element method is applied in this study. A series of simulations have been performed for the unstiffened panels have the cutouts with different shapes and sizes. Effect of size and cutout shapes to the ultimate strength of steel plates and different shapes of the structural. The relationship between stress and strain is investigated and analyzed. A relationship showed that the effects of different shapes of structural to ultimate strength is presented. The aim of this study is to evaluate the stress and ultimate strength of perforated structures with holes under the compression edge load. Which is the main action type arising from cargo weight and water pressure affecting the ships structure and offshore structures. The cutout is circular and elongated circular in the located in the center of the plate. A series of Abaqus nonlinear finite element analyses performed with cutout size is investigated. By regression analysis of the FEA results is obtained, it helps marine designers to give the optimum structure for simultaneous durability to ensure the maximum saving of raw materials.
