Functionally graded materials (FGMs) have become a focal point in materials science, capturing widespread attention for their versatility in diverse industrial applications. These materials exhibit a non-uniform composition, leading to dynamic variations in material properties across their depth. In this research, the intricacies of buckling behavior in square plates featuring perforations, constructed from FGMs are explored. A five-layer FGM plate, with varying perforation shape and perforation percentage forms the basis of investigation. Uniaxial load is applied with one end fixed, and the buckling load is scrutinized through eigenvalue buckling analysis. This comprehensive approach aims to provide insights into how diverse perforation configurations influence the structural integrity of FGM plates under the specific loading condition of uniaxial loading with one end fixed. The research seeks to contribute useful insights into optimizing the design and performance of FGM structures.
