| Abstract | The critical current (IC) of high temperature superconductors is an important parameter for practical application, such as magnets, cables and transformers. The degradation of IC under the tensile strain is measured at 77 K as well as under the compressive strain. It is found that the properties of Bi-2223 tapes are superior in the compressive strain to that in the tensile strain. The fatigue degradation behaviors of Bi-2223 tapes are studied in the symmetrical strain cycles and the unidirectional strain cycles. Both of the tests are conducted at 77 K. It is observed that the IC after thousands of cycles in the unidirectional strain cycles is much higher than that of the symmetrical strain cycles. Finally, a round bending test is employed to determine the degradation of IC when Bi-2223 tapes are wound around a mandrel. A critical radius of about 50 mm is found in the experiment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
