| Abstract | The assessment of the cold working, deformation, stress and strain distributions, and elastic spring back of superconducting cables conductors used for nuclear fusion experiments is a crucial issue for their manufacture process. The winding process of the ITER Toroidal Field (TF) conductors foresees their unbending from the drum they are delivered with and re-bending to their final shape. Nowadays the winding of the European Dipole (EDIPO) dummy coil is in progress and the final one will be challenging due to the conductors stiffness and the related spring back effect. In the light of this F4E ongoing activity and in view of the final design of the automatic winding process of the ITER TF coils a numerical tool capable to predict the plastic and elastic behavior of these conductors would be useful. To this end explicit Finite Element (FE) models have been implemented with the commercial code ANSYS/LS DYNA and simplified non linear calculations with CAST3M. Several numerical analyses have been performed by using different material properties, plasticity behaviors and loading conditions. The results of the analyses are presented and compared with experimental results and correlations with analytical solutions are investigated. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
