In the present work forming limit diagrams for extra deep drawing steel at room and elevated temperatures have been determined experimentally by conducting stretch forming operations using designed and fabricated warm forming tooling setup. With the help of FLDs formability of EDD steel has been analyzed and co-related with mechanical properties like strain hardening coefficient (n) and normal anisotropy (r -).Material properties of EDD steel are calculated at various temperatures and effect of these properties like work hardening exponent (n) anisotropy(r -) and strength of the material are co-related by FLDs at various temperatures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
