| Abstract | In using process, joints and fasteners always became the weakest area around holes and easy to generate initial damage. At current study, glass chopped fiber mat and unsaturated polyester were used to fabricate glass mat composite (GMC) plates. The influence of open-hole on mechanical property was investigated from tensile test. The decreasing ratio of notched strength from unnotched strength was compared with different size of holes to evaluate the influence of holes size on the sensitivity of GMC. Two sizes of drills, were employed to make drilling hole on the materials. Different damage areas in notched specimens were distinguished. Finally, in order to describe the property of GMC in resistance on open holes, the concept of characteristic distance was introduced. The values were calculated by finite element analysis software (MSC-Marc.) in linear elastic method. Furthermore, the characteristic distance was found that it had a good correspondence with damage characteristics. |

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.
