| Abstract | In this paper, a dislocation density-based finite element model is developed to study the behavior of twinning-induced plasticity (TWIP) steels in which mechanical twinning plays a significant role in the plastic deformation process. The model is calibrated for Fe-31Mn-3Al-3Si TWIP steel using experimental data. Comparison of the computational results with experimental observations suggests that the numerical model acceptably predicts the macroscopic behavior and the twinning content of the material. Next, the developed numerical model is employed to investigate some microstructural characteristics of the material. The effect of grain size on twinning is also studied. In addition, different loading conditions on a representative volume element are considered to reveal the existence of any relationship between twinning and triaxiality. |

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.
