| Abstract | The objective of this work is to study the crack-tip field of plane strain fully plastic crack growth of a single-edge cracked specimen subject to pure extension. The nodal release technique [1] was implemented into an FEM model so that the nodes arranged in the crack path are released. The fracture criterion for the crack growth in the model adopts the loading geometry-based crack-tip opening angle-(CTOA) proposed in the work of Ref. [2]. The crack-tip field from the CTOA-based crack growth was investigated and characterized with a slip line field. It was observed that the backface configuration of the specimen, which evolves with the crack growth, is engaged in the formation of the shear band and, as a result, significantly elevates the triaxiality at the crack-tip during the crack growth. |

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.
