| Abstract | The failure fate model of components based on the load-strength interference model is proposed, and the relationship between the failure rate of components and time in different cases is studied. The existing failure rate calculation methods of components are analyzed, and it is pointed out that these methods for calculating the failure rate of products are all based on the statistic analysis of fail data and can not reflect the relationship between the failure rate and the factors. Then, the failure rate model capable of embodying the effect of load and strength and its degradation is developed with the time-dependent load-strength interference. The results show that for the different combinations of load and strength, the failure rate curves of components are different and have the whole or partial characteristic of bathtub-shaped curve. The method proposed can present the relationship between the failure rate of components and the parameters of load and strength, and it can be used to calculate the failure rate of components accurately as long as the parameters of load, strength and the rule of strength degradation are known. Hence, it is more applicable for the reliability design and the lifecycle management of components. |

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.
