Abstract | The paper presents dynamic shear properties of magneto-rheological elastomers (MREs) under various loading conditions. It particularly focuses on characterization of MREs under compression-shear type combined loading, as it represents realistic loading conditions in various engineering systems and structures. In this study, MRE samples were fabricated by curing a two component elastomer resin with 30% content of 10 mum sized iron particles by volume. In order to vary the magnetic field during shear testing, a test fixture was designed and fabricated in which two permanent magnets could be variably positioned on either side of the specimen. By changing the distance between the magnets, the fixture allowed for varying the magnetic field that passes uniformly through the sample. Using this test setup and a dynamic test frame, a series of shear tests of MRE samples was performed by varying the magnetic field and frequency of loading. The results show the MR effect (percent increase in the materials ldquostiffnessrdquo) increases as the magnetic field increases and loading frequency increases within the range of the magnetic field and input frequency considered in this study. The results further show that the elastic modulus of the precompressed MREs increases as compared with that of MREs without precompression. |

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.
