  • Abstract:
  • Laminated composite materials are formed by fusing layers of at least two separate materials, functioning as a single entity. Lamination may emphasize attributes like as strength, stiffness, lightweight, corrosion and wear resistance, and acoustic insulation, among others. While cuts are inevitable in structures, the resultant gaps, when required, lead to a decrease in strength and stiffness. This work uses numerical methods to analyse the critical buckling stress of a laminated composite plate with cutouts by modifying the geometries of the cutouts in relation to the laminate's optimum fiber orientation. The buckling load-bearing capacity of laminated composite plates with square and rectangular cutouts is inferior to that of plates with circular cutouts. The arrangement of fiber orientations 0/90/15/-15/15/-15/0/90 combined with circular cutting yielded the maximum buckling stress. The buckling load increases with the elevation of the fiber angle in the inner layers.
