| Abstract | Design and manufacturing issues are here studied about the production of hollow structures made of an outer high resistance skin and a metal foam filler. These structures can be very useful as reinforcements against lateral impacts of vehicles. In car bodies, at the waistline or door height, the available space is very limited. Compact bars with light weight, high energy absorption efficiency and limited maximum deflection (i.e. high maximum load) are required. The skin of the proposed structure provides strength and stiffness and can be assembled to the vehicle body. The foam core provides energy absorption properties. The combination of non conventional technologies (hydroforming and metal foams) allows for the production of lightweight, high performance components, particularly suited for flexural resistance in terms of amount of energy absorbed for a given maximum load. A performance indicator y is proposed with the aim of comparing the performance of side impact absorbers with different cross sections and made of different materials. The tube hydroforming process is investigated as a suitable way for performance improvement of metal foam filled structures in side impacts, particularly for non-constant section bars. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
