| Summary: | The failure of a compression member has to do with the strength and stiffness of the material and the geometry (slenderness ratio) of the member. Whether a compression member is considered short, intermediate, or long depends on these factors. The buckling of hollow cylinder tubing is considered as failure due to elastic instability where the actual compressive stress at the point of failure is less than the ultimate compressive stresses that the material is capable of withstanding. For the purpose of this project few assumptions have been made which are the material element is homogeneous and isotropic, Hooks Law holds (stress linearly proportional to strain), the maximum stress the hollow cylinder can handle is equivalent to yield stress of material used which are steel and aluminum, the loads and the bending moment act in a plane passing through a principal axis of inertia of cross section and the deflection are small compared to cross sectional dimension. |
