In the present study, experimental and theoretical analyses were performed to predict the
failure strain of EDD and AA5052 sheet metals. In this context, uniaxial tensile tests and …

This paper aims to estimate and analyze both the necking and fracture based path-
independent forming limit criteria during two-stage forming of anisotropic sheet materials. In …

In this study, experimental and numerical investigations were conducted to predict the
formability and fracture behavior of as-received and pre-strained sheet materials during …

Anisotropic ductile fracture is of special importance for accurate modeling of failure in plastic
forming of lightweight sheet metals. This research introduces a user-friendly approach to …

This paper is concerned with modeling of fracture-based forming limit criteria for anisotropic
materials in sheet metal forming to predict the sudden fracture in complicated forming …

In present work, tensile and stack compression tests were performed along different
orientations to evaluate the yield behaviour and strength directionalities of several equi …

In this paper, the Gurson–Tvergaard–Needleman (GTN) damage model is used to
determine the forming limit curve of anisotropic sheet metals. The mechanical behavior of …

Accurate prediction of the formability in multistage forming process is very challenging due
to the dynamic shift of limiting strain during the different stages depending on the tooling …

The interpretation of sheet forming simulations relies on failure criteria to define the limits of
metal deformation. The common requirements for these criteria across a broad range of …

In this paper, failure limits of aluminum AA5052 sheet material were experimentally
investigated, and subsequently, these were predicted using various uncoupled ductile …
