1. Mechanical response under tensile stress
When subjected to tensile stress, All Aluminum Honeycomb Panel exhibits unique mechanical properties. As a panel, aluminum plate bears the main tensile stress, and its strength and ductility are crucial to the overall performance. Due to the presence of the honeycomb core, stress is transmitted to the honeycomb core structure through the aluminum plate. During the stretching process, the edges of the hexagonal honeycomb core will bear tensile force. According to the principle of material mechanics, the wall thickness, height and other parameters of the honeycomb core affect its tensile modulus. Thicker honeycomb core walls can better resist tensile deformation. At the same time, the distribution density of the honeycomb core also determines the uniformity of stress transmission. Under reasonable design, All Aluminum Honeycomb Panel can effectively disperse stress during stretching, avoid damage caused by local stress concentration, and show better tensile performance than solid aluminum plates of the same thickness.
2. Mechanical response under compressive stress
When subjected to compressive stress, All Aluminum Honeycomb Panel has excellent compressive resistance. When subjected to pressure, the honeycomb core begins to deform gradually. In the early stage, the wall of the honeycomb core mainly bears pressure and buffers external forces through its own elastic deformation. As the pressure increases, the honeycomb core will buckle locally. At this time, the structural design of the honeycomb core plays a key role again. The hexagonal honeycomb core has an advantage over other shapes in resisting buckling. At the same time, the aluminum plate constrains the honeycomb core to prevent it from excessive deformation. This synergistic effect enables the All Aluminum Honeycomb Panel to absorb a large amount of energy during compression and maintain structural stability within a certain range. It is widely used in scenes that need to withstand greater pressure, such as the supporting part of the building structure.
3. Mechanical response under bending stress
Under bending stress, the upper and lower aluminum plates of the All Aluminum Honeycomb Panel bear tensile stress and compressive stress respectively, while the honeycomb core plays a role in shearing and transferring stress in the middle. During the bending process, the shear modulus of the honeycomb core determines its ability to resist deformation. A reasonable honeycomb core structure can enable the All Aluminum Honeycomb Panel to maintain good performance at a smaller bending radius. Moreover, due to the presence of the honeycomb core, the moment of inertia of the plate increases, further improving its bending resistance. Compared with solid panels, All Aluminum Honeycomb Panel can effectively improve bending stiffness while reducing weight, and has important applications in fields such as aerospace that are sensitive to weight and need to withstand bending loads.
4. Comprehensive mechanical response under complex combined forces
In actual complex force environments, All Aluminum Honeycomb Panels are often subjected to multiple forces at the same time. For example, in building curtain walls, there may be bending forces caused by wind, pressure caused by deadweight, and tensile or compressive forces caused by temperature changes. At this time, the synergy of the various parts of the All Aluminum Honeycomb Panel becomes more complicated. Forces in different directions affect each other, and the connection between the aluminum plate and the honeycomb core needs to ensure sufficient strength to transmit complex stresses. Through finite element analysis and other research methods, it can be found that the internal stress distribution of All Aluminum Honeycomb Panel under this complex combined force presents a complex three-dimensional state. Reasonable structural design and material parameter selection can optimize its mechanical response under complex force environments and ensure its long-term stable use.
