| Abstract | The main objective in this paper is to develop an analytical solution of burst pressure for pipe elbow containing the effect of yield to tensile strength (Y/T) ratio. By non-linear regression analysis, available experimental data between the strain hardening exponent and Y/T ratio were fitted to mathematical models with high values of correlation coefficients. Meanwhile, in order to reflect the effect of different yield criteria on the burst pressure, the unified yield criterion is used and an analytical solution of burst pressure expressed as a function of parameter b, Y/T ratio, curvature impact factor and the ratio of thickness to radius is ultimately derived. Comparison with traditional theoretical results and numerical results shows that the present Mises results considering the effect of Y/T ratio match the best with numerical results. Validation with experimental results is carried out and the present TSS criterion provides the best agreement with experimental ones. Moreover, the effects of parameter b, strain hardening exponent, Y/T ratio, curvature impact factor, as well as the ratio of thickness to radius on the burst pressure are also discussed systematically. |

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.
