Finite Element Analysis of the Buckling Behavior of Laminated Carbon Fiber-Reinforced Plastic (CFRP) and Glass Fiber-Reinforced Polymer (GFRP) Rectangular Beams

  • PageNo: 1043-1047
  • Abstract:
  • This study examines the buckling behavior of rectangular carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP) beams using finite element analysis (FEA) in ANSYS. Composite materials are widely used in engineering applications due to their superior strength-to-weight ratio and customizable mechanical properties. The beam is modeled with multiple layers, incorporating various fiber orientations to assess their impact on buckling resistance. The analysis is performed under axial compressive loading, determining the critical buckling loads. The results emphasize the influence of material properties, boundary conditions, and geometric configurations on buckling performance. This research provides valuable insights for optimizing composite beam design to enhance structural stability.
