The classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is given in Eq.(1.6): (1.6)σh=Prt whereP, the internal pressure;t, the wall thickness;r, the radius of the cylinder. ...

No further guidance on local buckling stress or allowable compressive stress was given in the first five editions of RP2A. AISC also did not contain any guidance on local buckling for tubular members until 1978, when the 8th edition AISC was introduced, but AISC did contain formulae for overall...
The calculation formulae of normal stress difference,tangential stress and moment acted on the inner cylinder for the flow of power-law fluid in annulus with the inner cylinder executing a planetary motion under motive bipolar coordinate system were given. 给出了运动双极坐标系下幂律流体在内管做...
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 ...
Fatigue crack growth experiments were conducted on middle tension M(T) samples prepared in an orientation to simulate the hoop stress on the cylinder. The tests were conducted under constant amplitude loading at R ratio 0.1. The fatigue crack growth data was compiled and applied to simulate and ...
The results, which are normalized for the advantage of non-dimensional analysis show that the hoop wrapped functionally graded material cylinder, can significantly influence on the amount and distribution of stress intensity factors along the crack front....
The composite property distribution owns a distinct effect on the crack behavior in different directions that provides a clear guide to the maintenance of CNG cylinder. Finally an approximate formula with high precision is proposed to evaluate the stress intensity factor along the axial crack front ...
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.doi:US6694615 B2Roger D. Mickelson...
