Therefore, in this paper, the ring tensile tests were performed in order to evaluate the mechanical properties of high burn-up fuel cladding under a hoop loading condition in a hot cell.
Three distinct failure modes were observed: tensile axial failure at pure axial loading, weepage at axial dominated loading from 0.5 1 to 2 1 and localized leakage failure under hoop dominated loading of 4 1 and 1 0.
Six different stress ratios ranging from pure axial loading 0 1, 0.5 1, 1 1, 2 1, 4 1 and pure hoop 1 0 loading were tested.
Meniscal root attachments present one of the primary factors in maintaining resistance to hoop strain during load bearing.
The present work confirms the beneficial role of multiple hoops, low axial load, high confinement ratios and low values of the spacing of hoops normalized to the diameter of longitudinal bars on limiting the force response degradation due to cycling, as well as on enhancing the ductility of RC columns.
Due to tubesheet spring back after releasing the load, the hoop stress on both inner and outer surfaces is found to be compressive in most of the rolled tube length, but becomes tensile in the transition zone where it reaches a value of about half the yield strength of the material on the inner surface of the tube.
Moreover, stiffness of the strengthened columns is increased significantly due to the restraint offered by the external CFRP wrapping on hoop deformations during compressive loading.
Surprisingly, in the absence of any external loading, the hoop stress induced solely by the surface effects is identical to that in the corresponding case in a linearly elastic solid.
By attaching the menisci to the tibial plateau, the meniscal roots facilitate the dispersion of axial loads into hoop stresses (Bhatia et al. 2014).
But the bureaucratic process of the NHS for the gender reassignment program, it was just a load of hoops to jump through, really.
