Tube Wall Plasticity Behaviour of Different Hollow Sectional Tubes

A wide range of structural applications use hollow sectional tubes because of their high strength-to-weight ratio and structural efficiency. Optimizing the performance and design of these tubes requires a thorough understanding of the plasticity behavior of the tube walls. The tube walls plasticity behavior of hollow sectional tubes that are square, dodecagonal (twelve-sided), oval, and hexagonal (six-sided) under tensile loading is examined in this study using finite element analysis (FEA). Understanding how material characteristics, tube geometry, and loading circumstances affect these tubes plastic deformation and failure mechanisms is the goal of the research. When a load is applied to a tube wall that is greater than its elastic limit, the material deforms permanently due to plastic deformation. An analytical analysis was carried out to examine the structural behavior of hollow section tubes and their constituent parts, such as bolts, T-stubs, and hollow sections, as well as their failure mode, load–displacement curve, and load-carrying capacity. Important variables were found to have an impact on hollow section performance, including tube thickness and bolt types. In summary, the structural performance of hollow sectional tubes can only be maximized by having a thorough grasp of the plasticity behavior of tube walls. The results obtained from this investigation offer significant perspectives on the development and enhancement of hollow sectional tubes for diverse structural uses, resulting in the creation of more secure and effective constructions.
