A conventional bicycle wheel consists of a thin rim kept under high compressive stress by the (roughly normal) inward pull of a large number of spokes. It can be considered as a loaded column that has been bent into a circle. If spoke tension is increased beyond a safe level or if part of the rim is subject to a certain lateral force, the wheel spontaneously fails into a characteristic saddle shape (someti… WebMar 5, 2024 · is referred to as the slenderness ratio of the plate. Note that this is a different concept than the slenderness ratio of the column l / ρ. Using the parameter β, the ultimate strength of the plate normalized by the yield stress is. (10.6.9) σ ult σ y = 1.9 β. Recall that the normalized buckling stress of the elastic plate is.
Webbuckling capacity based on the stability landscape. This procedure consists of three steps: 1) shells are put under axial compression F a, 2) these axially compressed shells are probed in the radial direction at the location of a pre-existing imperfection, and 3) the peak probe force F p max and the corresponding axial compression F a
