prediction of variation in critical current with applied tensile bending strain of bi2223 composite tape from tensile stress strain curve
Journal of Applied Physics, 2010Co-Authors: Shojiro Ochiai, Hiroshi Okuda, M Sugano, Masaki Hojo, Kozo OsamuraAbstract:An approach to predict the variation in critical current with applied tensile/bending strain of Bi2223/Ag/Ag alloy composite tapes from the tensile stress-strain curves was presented. Three different fabrication-route samples were used to examine the applicability of the present approach. The damage strain parameter, referring to the difference between the tensile fracture strain and residual strain of Bi2223 filaments along the sample Length Direction (current transport Direction), was estimated from the variation in the slope of the tensile stress-strain curve. With the estimated damage strain parameter, the irreversible tensile strain for critical current was predicted, which agreed well with the experimental result in all samples. Also by substituting the estimated damage strain parameter into the core shape—incorporated model, the critical current-bending strain curve was predicted, which described satisfactorily the experimental result in all samples. The present approach could be a useful tool for ...

Prediction of critical current-bending strain relation of Bi2223 composite tape using residual strain of filaments, load-strain curve and geometry of cross-section
Physica C-superconductivity and Its Applications, 2009Co-Authors: Shojiro Ochiai, Hiroshi Okuda, Masaki Hojo, Kozo Osamura, J K Shin, H. Matsubayashi, Y. Mukai, Sohei Iwamoto, Mitsuhiko Sato, Masanao MimuraAbstract:Abstract A prediction method of the critical current–bending strain relation of the Bi2223 composite tape, which was bent at room temperature and cooled down to 77 K for measurement of critical current, was presented. The present method consisted of (a) measurement of residual strain of Bi2223 filaments at room temperature in the sample Length Direction by the X-ray diffraction method, (b) estimation of tensile fracture strain of the filaments from the analysis of the load–strain curve at room temperature, (c) measurement of geometrical factors such as the thickness of the sample and shape of the core by observation of the cross-section with optical microscope, and (d) calculation of the critical current as a function of bending strain by using the measured parameters mentioned in (a)–(c). The predicted variation of critical current with bending strain by the present approach described well the experimental one.

modeling analysis of the critical current of bent bi2223 composite tape based on the damage strain parameter and the shape of the core
Superconductor Science and Technology, 2007Co-Authors: Shojiro Ochiai, Hiroshi Okuda, M Sugano, Masaki Hojo, T Matsuoka, J K Shin, Kozo OsamuraAbstract:We present a new modeling approach to describe the relation between the critical current and the applied bending strain of a multifilamentary Bi2223/Ag/Ag alloy superconducting composite tape. In the model, the shape of the superconducting core, in which the Bi2223 filaments that transport the superconducting current are embedded in Ag, and the damage strain parameter, defined as the difference between the intrinsic tensile fracture strain and the residual strain of the filaments in the sample Length Direction (= current transport Direction), are combined with the exerted strain distribution in the bent sample. The extent of the damage to the core and the corresponding critical current are expressed as a function of bending strain. The present approach describes well the measured critical current–bending strain relation for the three different fabrication-route samples.
