This paper deals with the determination of numerical and experimental buckling loads for circular plates. In the study, plates made of isotropic material and laminated composites were taken into consideration. For the experimental part of the study, a buckling apparatus for circular plates (BACIP) was designed and manufactured to apply radial compression on plates simply supported along the outer edge, which was the most important aspect of the study. Experimental buckling loads were determined by connecting this apparatus to a tension machine. ANSYS software based on the Finite Element Method (FEM) and the analytical buckling load formula found in textbooks were also used for the determination of the numerical and analytical buckling loads. The effects of parameters such as plate thickness, number of layers, cutout sizes, and so on on critical buckling loads were investigated within the scope of the work. Comparisons of analytical, theoretical and experimental buckling loads were presented in both graphical and tabular form. The results of the experimental and theoretical buckling were found to be comparatively compatible.

本文讨论了圆板屈曲载荷的数值和实验确定。在研究中，考虑了由各向同性材料和层压复合材料制成的板材。对于该研究的实验部分，设计并制造了圆板屈曲装置（BACIP），以对沿外边缘简单支撑的板施加径向压缩，这是该研究最重要的方面。通过将该装置连接到拉力机来确定实验屈曲载荷。基于有限元法 (FEM) 和教科书上的解析屈曲载荷公式的 ANSYS 软件也用于确定数值和解析屈曲载荷。板厚、层数、切口尺寸等参数的影响 在工作范围内对临界屈曲载荷等进行了研究。分析、理论和实验屈曲载荷的比较以图形和表格形式呈现。实验结果与理论屈曲结果比较吻合。
