whereP, the internal pressure;t, the wall thickness;r, the radius of the cylinder. The SI unit forPis Pascal, whiletandrare in meters. If the pipe is closed on the ends, any force applied to them by internal pressure will induce anaxial orlongitudinal stress(σl) on the same pipe wal...
The method enables the stress in the end slabs resulting from internal excess pressure to be compensated without special arrangements in these slabs. By increasing the hoop prestressing towards the ends, the inertia axis of the respective slab is displaced towards the axial centre of the vessel. ...
While the internal pressure present in the cladding during the fuel lifetime can be replicated through use of pressure burst testing, other testing techniques are necessary. In pressure burst testing a mixed-mode stress state is present where both hoop and axial stress is induced in the test spe...
The residual stress for the original and the repaired welds was expressed as a logarithmic function in terms of axial bending stress, hoop bending stress,... Z Chen,P Wang,WZ Xiong - 《International Journal of Pressure Vessels & Piping》 被引量: 0发表: 2021年 Design of support structure fo...

The cables can be circumferentially stressed and there is a layer of insulation between teh calb...
PRESSURE-VESSELSIn this paper the fracture behavior of the compressed natural gas (CNG) cylinder with hoop wrapped composite layer is investigated for the axial crack at the inner surface. By the aid of the three-dimensional finite element method, the stress intensity factors along the crack ...
