If there exist an external pressure poand an internal pressure pi, the formula may be expressed as: σL=(pi−po)D4tσL=(pi−po)D4t It can be observed that the tangential stress is twice that of the longitudinal stress. σt=2σLσt=2σL ...
A formula is given for calculating the J-curves that associate the dimensionless J-integral with the dimensionless load. The stress-strain state of a thin-walled vessel with a surface half-elliptical crack and an internal elliptical crack is analyzed in a volumetric setting. The peculiarities of ...
Thin-walled pressure vessels are one of the most typical applications of plane stress. Consider a spherical pressure vessel with radius r and wall thickness t subjected to an internal gage pressure p. For reasons of symmetry, all four normal stresses on a small stress element in the wall ...
Large-diameter, thin-walled vessels are best supported near the heads, provided the shell can take the load between the saddles. The resulting stresses in the heads must be checked to ensure the heads are stiff enough to transfer the load back to the saddles. 3. Thick-walled vessels are be...

One can also get a sense of how small this load is by a simple mechanical thought experiment: Suppose the tube were not an origami but instead a homogenous thin-walled cylinder. Then, due to force balance, an internal pressure p as above would generate a hoop stress σ ∼ pR/h ...
For perspective, current clinical brain interventions use a pressure of 7 bar for some typical treatments. One can also get a sense of how small this load is by a simple mechanical thought experiment: Suppose the tube were not an origami but instead a homogenous thin-walled cylinder. Then, ...
A hollow,thin-walled tube has a rectangular cross-section as shown. If its wall experiences the shear flow of 900 N/m, determine (a) The average area of the tube, (b) The shear stress acting around the perimeter of the tube, (c) The magnitude of the tor ...
Then, dynamic response simulation of superalloy thin-walled structure under the same load as experiment was implemented, and fatigue life was estimated based on the fatigue life prediction model which mainly included: improved rain-flow counting method, Morrow average stress model and Miner linear ...
