Topic of Research Seminar: Numerical Analysis of Formability Characteristics of Steel Tailor Welded Blanks Formed through Single Point Incremental Forming

Abstract: Tailor Welded Blanks (TWBs) are being used extensively in industries like automotive, air, vessel, medical etc. Incremental forming has the potential to fully exploit advantage of these blanks. Incremental forming of homogeneous and heterogeneous aluminum and steel sheets welded through friction stir welding (FSW), laser or electron beam technology have been explored extensively by researchers both experimentally and numerically. However, research on formability of manually welded steel blanks using Tungsten Inert Gas (TIG) is meager. The paper highlights numerical analysis of formability of manual TIG welded steel sheets using Finite element software, Abaqus. Dynamic explicit method was used during numerical analysis. Variable wall angle pyramid was used as test geometry. State of stress and strain along other important findings were recorded which can be suitably applied to assess quite accurately characteristics unique to several kinds of manually welded TWBs.
