Computational Analysis of the Effect on Buckling Behavior of Supported Composite Plates Using a Static Structural Tool

In this paper, a numerical investigation of the effect of the buckling behavior of the supported GFRP composite plate is conducted using finite element analysis. FEM is employed to perform detailed research of buckling behavior for GFRP composites(beam, slab and column like structure). In this investigation, there were 1000 mm-long GFRP composite beams, 500 mm by 500 mm plates, and columns of height = 1200 mm. All of these components are subjected to axial and lateral loads. And all these parts are subjected to axial and lateral loads. The Young's modulus and Poisson's ratio of GFRP composites are 40 GPa and 0.3 respectively. The numerical value is defined by the substance. Numerical results presented in this paper are performed for various laminate configurations, including cross-ply, unidirectional, and bidirectional laminates, where the fiber content is 60% by volume. The buckling stress of the composite beams could be varied from 8 to 15 kN, and the critical load for plates or more complex shapes could be between 5 and 10 kN, depending on how the laminate is made. It is known that axial load factors have a substantial impact on the buckling of columns. The critical load may range from 10 kN to 20 kN, depending on the column's aspect ratio. Results indicate that finite element modeling (FEM) is an effective and reliable technique for predicting the buckling behavior of GFRP composites. They also provide essential information on the design of GFRP beams, plates, and columns for buckling.
