| Abstract | This paper presents a new approach of combining the Marciniak and Kuczynski (M–K) theory and the shear localization criterion (SLC) to determine the formability of light sheet materials. Due to the difficulty in determining the imperfection orientation under the uniaxial tension conditions, the M–K theory was only used to predict the right hand side (RHS) of the forming limit diagram (FLD), while the left hand side (LHS) of the FLD was predicted by the SLC as it has the advantage of dealing with strain path non-linearities. At the conjunction point between the LHS and RHS of the FLD (i.e. the plane strain conditions where minor strain ε 2 = 0), the critical plane strain was first calculated by using the M–K theory, and it was then used to determine the parameters involved in the SLC. As a consequence, the proposed combined model was employed to predict the formability of two typical light sheet materials, Mg alloy AZ31B and Al alloy AA5754-O, at elevated and room temperature (RT) respectively; the predicted results showed a good agreement with the experimental results. Therefore, the combined model of M–K theory and SLC is able to provide a new effective numerical modelling for formability prediction in the thermal and RT forming of light sheet materials. |

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.
