| Abstract | The use of lightweight materials offers substantial strength and weight advantages in car body design. For characterization of capability of sheet material dedicated to deep drawing processes in the automotive industry, mainly Forming Limit Diagrams (FLD) are used. However, investigations conducted at the Institute for Metal Forming Technology using new specimen geometries have shown that formability of High Strength Steel Sheet Material changes by superposing shearing on in-plane tension loads. Hence, these mixed stress and strain conditions including shearing effects can occur in deep-drawing processes of complex car body parts. But these changes in materials formability nowadays cannot be described sufficiently by using conventional FLC-criterion. Considering such aspects in defining suitable failure criterions a new semi-empirical model has been developed considering the effect of shearing in sheet metals formability. This novel model is capable to separate shear and in-plane tension loads by using a special strain definition. For experimental calibration of so called Shear Forming Limit Curve (SFLC) several standardized and enhanced material testing procedures with novel specimen geometries are necessary. In this contribution firstly the need of enhanced material description and additionally the theory SFLCModel is presented. For experimentally calibration required input parameters are determined by special specimen geometries. |

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.
