Elastic Buckling Behavior of Thin Plate with Circle Holes under Axial Compression

The stability of members will be affected because the stress concentration resulted from the holes in thin plates. Elastic buckling performance of the perforated circle plate under axial compression is analyzed using a general finite element software ABAQUS in this paper. Results show that the buckling stability coefficient of plate is significantly low when the hole locates at the short side of the plates. The buckling stability coefficient of plate will decrease with the increase of the dimension of holes when the hole size is less than a certain value. The buckling mode of plates will change because of the dimension of holes. Finally recommended calculate formula of buckling stability factor k of perforated circle plate under axial compression is presented based on parameter analyse.
