thick-walled cylinderThis paper proposes the superposition and unloading methods to realize different gradients and certain residual tension in winding tension design, and to clarify the relationship between hoop winding and residual tensions. The integral relationship between the winding and residual ...
There could also be aradial stressespecially when the pipe walls are thick, but thin-walled sections often have negligibly smallradial stress(σr). The stress inradial directionat a point in the tube orcylinder wallis shown in Eq.(1.8): ...
σh = hoop stress pi = internal or external design pressure pe = external design pressure D = nominal outside diameter of pipe t = minimum pipe wall thickness For relatively thick-walled pipes, where the ratio D/t is equal to or less than 20, a more accurate hoop stress calculation meth...
The hoop strains, after being averaged over the observed circumference, are prese−nted in (Fig. 11(a)) as a function of the average hoop stress, h , which was calculated by treating the tube as an thick-walled cylinder using the Lamé equa- tion, with radial integration of the ...
A Segmented Cylinder Test for Determining Hoop Stress in Composite Structures The usefulness of a cylinder test for obtaining hoop strength design data for glass fiber composite structures is well recognized. The advantage, theoretically, is primarily in the "statistical" value of fiber strength if un...
In present work, after finding the anisotropy resulting in dissimilar properties in different orientations of a thick-walled cylinder, experimental and numerical study was performed to reveal the fatigue crack growth behavior of the cylinder under cyclic hoop stress. Fatigue crack growth experiments ...

By the aid of the three-dimensional finite element method, the stress intensity factors along the crack front are obtained for different crack profiles. The effects of the cylinder geometry, hoop wrapped layer thickness and the property distributions of the composite layer on the stress intensity ...
The seal is spaced away from the circumferential weld that joins the end plug to the cylinder to reduce the hoop stress in the tube adjacent the weld, thereby reducing the tensile stress at the weld joint.Mickelson, Roger D.
