According to Newton's first law of motion, the hoop stress yields, Remarks • The above formulas are good for thin-walled pressure vessels. Generally, a pressure vessel is considered to be "thin-walled" if its radius r is larger than 5 times its wall thickness t (r > 5 · t). ...
57. In the context of thin rings, what happens to the hoop stress as the radius of the ring increases?Hoop stress increases linearly with radius Hoop stress decreases linearly with radius Hoop stress is inversely proportional to the radius Hoop stress remains constant...
So, changing the string out to a higher-yield-stress pipe, like P110 tubing, would impact the buckling force. Three means of raising this critical snubbing force value exist: • Increase the OD of the pipe • Increase the wall thickness, tw • Use a higher-yield-strength pipe Again...
Xi et al. (Xi et al., 2016) studied the influence of spinning process parameters on wall thickness deviation and diameter expansion, and pointed out that the thinning rate was the main factor. Based on the finite element simulation analysis and single factor experiment, Sun et al. (Sun et...
theoretical model for predicting springback angle of the stainless steel tube in terms of bending radius ratio and wall thickness ratio in rotary draw bending production. Zhang et al. [39] evaluated the springback of the tube in complex stress state based on a theoretical method, which was ...
The conditions of the applicability of the hoop stress in a thin sphere as an effective stress in strength criteria and corrosion kinetics models are specified. Formulae for the prediction of the lifetime are obtained in terms of both wall thickness and maximum stress. An algorithm of ...
In addition to the simplified equations, this study reveals that the thickness (i.e. inner and outer diameter) of the press-fit components does not play a significant role when calculating hoop stress in thin-walled press-fit components, contrary to current solutions which depend on the ...
Hoop tensile plastic strain corresponds to radial outward deformation, while hoop shrinkage plastic strain corresponds to radial inward deformation. In addition, the influence of axial constraint on the formation process and results of hoop plastic strain, as well as the effect of heating zone width ...
The normal stress is given by the axial tensile force, F in the longitudinal direction and the shear stress is given by the torque T, as shown in Figure 2a. Figure 2. (a) Crack in tube wall at an angle ∅∅ with the tube axis; (b) Approximate formula for thin-walled circular ...
