| Abstract | The current theory of the strength of solids is supplemented by an account of thermodynamic linear tension and its variations in the course of crack growth. For the case of dispersion interactions, two mechanisms of crack growth are compared, i.e., the conformal mechanism (when the angle at the crack tip is conserved) and the depth mechanism (when the width of crack mouth is conserved); it is shown that the second mechanism is more energy favorable. For both mechanisms, as well as for the case of constant linear tension, relations for the ultimate strength are derived, irrespective of the type of interactions, which clarify known Griffith and Sack criteria for linear and disc-like cracks, respectively. It is established that the role of linear tension in similar criteria increases with the narrowing of the crack and becomes significant in nanocracks. It is shown that an increase of linear tension upon the introduction of sorbate into the crack does not interfere with the effect of adsorption-induced reduction of strength (the Rehbinder effect). |

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.
