Pipe Axis - an overview | ScienceDirect Topics
Two stainless steel wires were attached to the pipe in one plane, to ensure that motions occur normal to that plane. The pinned, axially-sliding lower end was achieved by a short bar perpendicular to the pipe axis, in contact with the pipe.
The Intriguing Stresses in Pipe Bends | COMSOL Blog
Jan 31, 2023 · Beam theory predicts that the axial stress has its peak values at the inner-most and outer-most fibers in the bend plane. But, defying beam theory, the opposite happens! As shown in the animations, the von Mises stress distribution reaches its …
Problem 2-5: A cylindrical pipe of 160-mm outside diameter and 10-mm thickness, spirally welded at an angle of =40 o with the axial (x) direction, is subjected to an axial compressive load of P=150 kN through the rigid end plates (see below).
Pipe bends subjected to an opening in-plane bending moment will have a deformed oval cross-section with the major axis in the plane of bending as shown in Figure 2 (Shalaby M. et al. 1999).
Axial In-Place Behaviour of Unbonded Flexible Pipes
Oct 13, 2022 · The axial behaviour during the in-place phase can be consistently defined by a transition plane and this can be implemented in the in-place analysis. Reduced risk for upheaval buckling of flexible pipes and removal of excessive conservatism can be achieved.
A mechanical model of axial and circumferential bidirectional ...
Jul 23, 2021 · In the paper, the mechanical model of axial and circumferential bidirectional deformation of large thin-walled pipes has been investigated in the process. Most of the mechanical models proposed are based on a single direction.
Mechanical Behavior of Polyethylene Pipes under Strike-Slip Fault ...
Feb 28, 2022 · The axial strain in the pipe region between the two buckling points increases with the decrease of fault moving speed. Furthermore, it can be observed that the distance of the buckling position from the fault plane is increased when the speed is increased.
(2) In the case of the pipe he assumes that the turbulent components are symmetrical about the axis of the pipe and confined entirely to axial planes, so that no particle can ever cross the axis.

Pipe geometry effect on fatigue cracking location of 90° elbows …
Sep 27, 2023 · The most important parameter affecting fatigue crack location is found to be the mean radius-to-pipe thickness ratio, r m /t. When r m /t <4–5, the circumferential crack at outer intrados is predicted. Otherwise, when r m /t >4–5, the axial crack at inner crown is predicted.
