| Abstract | In this paper, a 3-dimensional mathematical model has been developed for the thermo-mechanical coupled analysis of the solidification process of carbon steel in funnelshaped mold using thermo-elastic-plastic finite element method (FEM). The major application of the model is to perform computations of temperature, stress and longitudinal cracking index (LCI) variations in shell. The effects of casting speed on stress and LCI are discussed. The results show that the temperature at the thin slab off-corner of wide face is higher than the temperature at the center of the wide face and narrow face, the temperature history at the thin slab off-corner appears two plateaus at 280mm and 840mm below meniscus, and the peak stress of solidification shell occurs at the region of funnel edge, where the shell has high cracking susceptibility. The LCI is high at the wideface center, funnel edge and off-corner of thin slab wide face. Increasing casting speed within certain range can decrease the LCI of original shell and reduce the possibility of longitudinal crack. |

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.
