| Abstract | Accurate numerical calculation of stresses in structures with a multitude of spot joints continues to be a challenge, especially if local stresses are located in the area of joining positions or if crack endangerment needs to be addressed. In addition to inadequate FE modelling, a major cause for this is the unavailability of exact primary data, which describe the properties of the joints. New methods for determining the stiffness behaviour of joint connections bases on the measurement of the relative displacement of the sheet metals between the joints during applying a load. The measured relative displacement is proportional to the deformations in the joint area. Strain of the test specimen as well as deformations of the load frame or the force measuring cells have no effect in the relative displacement. Two test methods and the necessary measurement technology will be described. On the one hand a method for symmetric joint connections will be shown and on the other hand a method for unsymmetrical pairings of sheets. For the first case a 2- point-shear-load-specimen is used, for the second a 3-point-torsion-test. |

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.
