| Abstract | An investigation based on experimental and finite element (FE) studies was carried out to understand the failure mechanisms of scarf-repaired T700SC/NY9200GA composite laminates under tensile load. Test specimens were categorized into 4 groups based on the type of scarf patch (pre-preg and pre-formed) and scarf angles (6°and 10°). A 3-D progressive damage accumulation model was developed to understand the damage mechanisms and predict the ultimate strength of repaired laminates. Damage characteristics of specimens were observed by optical microscope and scanning electron microscopy. Test results have shown that the laminates repaired with pre-preg scarf patch and 6° scarf angle have higher failure strength. It was also found that the fracture morphology of failed laminate is different but failure mode was found to be the same. The crack initiated from highly stressed adhesive regions and then circumferentially propagated throughout the adhesive interface thus causing adhesive failure. FE results were found to be in good agreement with experimental results. |

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.
