| Abstract | Parameters setting in numerical simulation of Fluid-Structure Interaction (FSI) is important to get accurate results. A variable without units was defined to describe the mesh density. Effects of that variable and coupling control parameter in numerical simulation of FSI were studied. As an example, the underwater contact explosion on circular plate was simulated using the FEM programe LS-DYNA. The results of numerical simulation were compared with experimental data. The results showed that calculation errors were reduced at first and then increased according to the mesh density increased. Optimum range of mesh density was 2¨C3 and ratio of fluid mesh density to structure mesh density was 2¨C1. The optimum aspect ratio of structure mesh does not exceed 2. Penetration could be modified through adjusted coupling control parameters. The modifying way had no effect on structural deformation and fracture. |

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.
