The buckling strength of thin plates with a cut-out subjected to axial compression is investigated. Some other reports have reported the problem of the stability of the square plate with a circular hole. However, there is no indication of the study which introduces the effect on the buckling value with a square cut-out rounded corner in a plate. The results of numerical analysis and experimental study for the buckling of the square and rectangular thin plate with a square cut-out having rounded corner curvature are presented. Furthermore, the relation between the stress concentration and buckling coefficient are discussed in this report. The edge conditions of the plates are all simply supported.
