| Abstract | Creep behavior of nano-silver paste films has been studied over the tensile stress range from 2 MPa to 7.5 MPa and the temperature range from 100°C to 175°C. In this study, all creep tests were conducted on a micro uniaxial fatigue testing system (MUF-1020). It was observed that, under the above test conditions, the steady-state creep rate of the films, $$ \dot{\varepsilon } $$ , could be sufficiently described by a power-law creep equation in which both the tensile stress and the temperature were involved. Creep rupture life was analyzed by the following two methods: the Monkman–Grant relationship and the θ projection concept. Based on accurate measurement of the creep strain rate, the prediction of creep life by the Monkman–Grant relation is very close to the test results. The θ projection concept is not only an effective way to predict the creep life, but also an appropriate approach to determine a precise value of creep strain rate. In addition, the Kachanov damage evolution law was employed to investigate the damage evolution of the films. The study showed that the process of damage evolution of the nano-silver films was temperature independent for all tests performed. |

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.
