This paper presents, in terms of the spherical section assumption, an effective method for determining the local stress and limit load of a thick-walled tube with an external hoop direction U-shaped notch under tension, and discusses the relationships of the stress concentration factor with notch ...
The outer tube is shrunk on to the inner tube, and the radial stress at the common surface owing to shrinkage is 30 MN/m^2. Find the ma Determine the change in volume of a thin cylinder of original volume 65.5 \times 10^{-3} m^3 an...
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 ...
on the amplitude bending stress is discussed, It is evident that as increase of the pressure would have an adverse effect on the bending stress rates of the specimens specimens for all fiber orientations, this is due to the pressure increasing the circumferential stresses within a specimens wall...
The hoop residual stresses in the FGM ring varied in the range of 50 to +35 MPa and from tension at the inner surface to compression at the outer surface because of the graded composition. With an increase in wall thickness and/or composition gradation, the residual stresses were found to ...
