Geometrical buckling
WebTo highlight the high sensitivity of the dynamics to the resonator’s geometry as function of the critical buckling, we use the ROM to examine the effect of a 5 % reduction in the thickness of the resonator. By referring to the thickness of the identified resonator in Table 2 as h ID, we express a 5 % reduced thickness as h = 0.95 h ID. 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 …
