| Abstract | A number of factors across multiple length scales (Table 1) may contribute to the mechanical competence of bone (i.e., the resistance to fracture). This structural complexity hinders a complete mechanistic explanation (model) for elderly bone fragility. Although age-related loss of bone mass has been viewed as the reason for the rising incidence of bone fractures in the elderly,(2) bone quality is more meaningful to provide insights into why individuals with ‘normal’ bone mineral density (BMD) suffer fractures. Bone is a hierarchical and hydrated composite of mineral and collagen phases,(3, 4) showing a rather complex response to the mechanical loading.(5, 6) While previous research has investigated the resistance of bone to crack propagation,(7, 8) fatigue behavior,(9–11) and mechanical changes to load-induced damage,(12–14) little is known about the mechanical behavior of bone as a function of progressive deformation (strain). In this study, by employing a previously developed progressive loading scheme,(15) we intend to investigate the progressive stress-strain behavior of bone with increasing strain levels, so as to gain more information on the underlying mechanisms for post-yield behavior of bone. It is hypothesized that the post-yield behavior of bone varies with the increasing strain, which plays a significant role in sustaining the toughness or quality of bone. |

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.
