To study the influence of surface fatigue cracks on the static strength of circular tubular T-joints, experimental tests on four full-scale circular tubular T-joints are carried out. Firstly, surface fatigue cracks are prefabricated by fatigue test in three circular tubular T-joints. Thereafter, experimental tests on the static strength of all the circular(More)
The existence of charge-density-wave (CDW) correlations in cuprate superconductors has now been established. However, the nature of the CDW ground state has remained uncertain because disorder and the presence of superconductivity typically limit the CDW correlation lengths to only a dozen unit cells or less. Here we explore the field-induced 3D CDW(More)
Charge density wave (CDW) correlations have been shown to universally exist in cuprate superconductors. However, their nature at high fields inferred from nuclear magnetic resonance is distinct from that measured with x-ray scattering at zero and low fields. We combined a pulsed magnet with an x-ray free-electron laser to characterize the CDW in(More)
