Analysis of plastic flow localization under strain paths changes and its coupling with finite element simulation in sheet metal forming
Formability of sheet metal is usually assessed by the useful concept of forming limit diagrams (FLD) and forming limit curves (FLC) represent a first safety criterion for deep drawing operations. The level of FLC is strongly strain path dependent as observed by experimental and numerical results and...
