Analysis and Optimization of Mechanical Behavior of Multi-Level Reinforced Panels
Three-point bending experiments and finite element simulation methods are used to analyze the deformation and damage of multi-level reinforced panels.Two reinforcing patterns are introduced:ortho-hexagonal and concave-hexagonal.The research objects include the reinforced panels with different transverse and longitudinal reinforcing rib wall thicknesses,the right-angle boundaries optimized with rounded chamfers,and the secondary reinforcement structures.To analyze the effects of transverse and longitudinal reinforcing rib wall thickness,optimized rounded chamfer,and secondary reinforcement structure on the structural strength and mechanical behavior of the reinforced panels with given geometric parameters.The results indicate that the structural strength of the reinforced panel increases with the increase of transverse and longitudinal reinforcing rib wall thickness,and the longitudinal reinforcing rib wall thickness has a greater impact on the structural strength.The concave hexagonal reinforcement pattern has a higher load bearing capacity than the orthogonal hexagonal reinforcement pattern.Introducing the optimized rounded chamfer can significantly mitigate the stress concentration at the edges and corners,leading to enhancement of the structural strength of the reinforced panel.The load carrying capacity of the secondary reinforced panels is significantly improved,and the improvement is most pronounced when the secondary reinforcement incorporates concave hexagonal cells.
