| Abstract | The numerical research of vibro-acoustic response to fluid-structure-fluid coupling system caused by acoustic loading needs to be conducted with the help of reliable structural finite element and acoustic boundary element to complete the fluid-structure-fluid coupling calculation. In this paper, discrete Kirchoff quadrilateral (DKQ) bending element and constant strain quadrilateral (CSQ) membrane element is adopted to construct DKQ-CSQ shell element of high accuracy. Therefore, a BEM-FEM numerical solution method of high accuracy is created. With this method, the vibro-acoustic response to the acoustic loading on a shell which is not only surrounded by but also filled with fluid can be solved. Numerical calculations of spherical shell are carried out, and the accuracy of the method is verified in this paper. The influence of different fluid media on echo intensity and structural vibration mode are analyzed in detail. |

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.
