Deformation in Multilayer Fiberglass Beams at Different Positions of Concentrated Load

We analyzed the load and deformation in hollow beams made from multilayered glass-fiber-reinforced polymer, specifically assessing deformation under concentrated load. We performed nonlinear numerical analysis on beam with rectangular cross-sections with set dimensions and material properties. Beams with three different spans were analyzed, loaded with two concentrated forces at varying distances between applied force and supports. As the force was increased, we assessed the deformation near the supports. These results are shown in dimensionless diagrams, where the ratio of the applied and initial force correlates to the ratio of deformation near the support to deformation near the mid-span.
