| Abstract | This paper proposes a procedure to the robust design of composite laminates with initial imperfection under probabilistic considerations. A probability progressive failure mode of composite laminates is adopted to evaluate the structural reliability. The initial imperfection, strength parameters are considered as random variables, matrix cracking and fiber breaking are defined as the two basic failure modes. Ply-level failure probability is evaluated by the first order reliability method (FORM) and system reliability is computed based on the significant failure sequences. A structural optimization problem is solved with the fiber orientation and the lamina thickness as the design variables, the maximization of the system reliability index as the objective. Finally, robust design method for laminates is presented and discussed. |

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.
