Abstract | Stamp forming method used for forming of relatively smaller and complex-shaped fiber metal laminate (FML) parts has inherent constraints such as fiber sheet rupture, metallic layers quantity, and repeated heating/solidification of thermoplastic (TP) resin/tooling. As an alternate and efficient strategy, simultaneous forming of multiple blanks has been studied by using hydro-mechanical deep drawing (HDD) method. Also, the effect of process variables such as cavity pressure and blank holding force (BHF) and their role in wrinkles formation, thinning, edges movement and formability for the HDD process (performed with and without applying the cavity pressure) has been deliberated. Blanks made of Al 2024-O alloy sheet were used and the formability attributes, based on Barlat 2000 yield criteria, were estimated using DYNAFORM/LS-DYNA and compared with the experimental results. The results show that application of cavity pressure within certain limits has a positive effect on the quality of three-layer formed part as well as leads to higher depths as compared with the process when no cavity pressure was applied. Good agreement has been found between the predicted and the experimental results. The simultaneous forming strategy can give the advantage of eradicating the strict process controls which are needed in the conventional stamp forming method and can expand the application areas of FML parts for the aerospace and automobile industries. |

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.
