| Abstract | Inverse problems in mechanics of solids and structures are gaining more importance. One of the reason behind that is the advances in digital image processing and computer vision technologies. Traditionally, the user would locate features on the object or attach grids to it. The deformation of those features (or grids) would give an indication of the displacements undergone by some points on the surface of the object due to the deforming forces. Knowledge of the deforming forces and the displacements is usually enough to approximate the material properties of the object. In this paper we suggest a method by which a featureless object can be interrogated for its material properties. No invasive procedures are necessary. The method uses geodesics of the deformed and undeformed surfaces to obtain the displacements due to known deforming forces. Finite element method is then used to deduce the material properties distribution of the object. The method is proven to work only for elastic deformations that would leave a deformed surface developable with respect to the undeformed one. |

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.
