Abstract

Plate one of the popular structural elements used in a wide range of industries and structures, often failed by buckling due to subjected compressive stresses and shear loads. In its application, sometimes making holes through plates is needed. the finite element parametric studies demonstrate that holes may create unique buckling modes, and can decrease critical elastic buckling stress depending on the size and location of holes. This study investigates buckling of plates with through-thickness holes. The effects of size of hole as well as teh effects of thickness of the plate on critical load of plate having holes are analyzed and investigated by using finite element method(FEM) by using software ABAQUS. Then by using the Gerard and Becker equation compressive buckling coefficients, Kc, are calculated and presented to enable designers to calculate buckling load for the desired plate with holes in specific dimension.
