External pressure on a thick walled cylinder
WebJan 16, 2024 · External pressure stresses add to the axial compression stresses since they are in the same direction. In addition, the hoop stresses resulting from external pressure reduce the ability of the cylinder to resist the overall axial load. The uniform circumferential compressive forces from external pressure aid in the buckling process. WebConsider a thick cylinder subject to internal pressure p 1 and an external pressure p 2. Under the action of radial pressures on the surfaces the three principal stress will be σ r …
