| Abstract | An analytical method of calculating the tensile strength of composites, with perfectly bonded and randomly oriented short fibres, was described recently in this journal by Zhu et al. '1'. When comparing the calculations with experimental results for aluminum alloys, reinforced with Al2O3 fibres in a three-dimensionally random array, the conclusions were incorrect. The authors did not recognize that in this type of composite, the transverse fibres often delaminate. This paper describes an alternative and simpler method of calculating the tensile strength, which includes both perfect bonding and the effect of delamination. This method has been applied previously to two-dimensional random systems and is here extended to three-dimensional systems. The calculated values of strength are in excellent agreement with the experimental values quoted by Zhu et al. Further support is provided by comparisons with more extensive data for other metal matrix composites. General conclusions for a three-dimensional random system are that: (i) perfect bonding will only provide a modest increase of strength; and (ii) delamination of the transverse fibres will drastically reduce the strength and cannot be tolerated. |

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.
