| Abstract | In this paper, the interactive influences of notch severity and test temperature on the impact properties and fracture behavior of a Al-Cu-Mg alloy 2024 in the T351 microstructural condition is presented and discussed. Notch angles of 45, 60, 75, and 90° were chosen for a standard Charpy impact test specimen containing two notches. For a given angle of the notch, an increase in dynamic fracture toughness, with test temperature, is most significant for the least severe of the notches, i.e., 45°. At a given test temperature, the impact toughness decreased with an increase in notch severity. An increase in notch severity resulted in Mode I dominated failure at all test temperatures. The influence of localized mixed-mode loading is minimal for the alloy in the T351 microstructural condition. The impact fracture behavior of the alloy is rationalized in light of alloy microstructure, mechanisms governing fracture, and the deformation field ahead of the propagating 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.
