The Light Metals Best Paper Award
2007 winner –
M. Worswick, O. Orlov, S. Winkler, Z.T. Chen for their paper
entitled:
“Simulation and Formability of Automotive Aluminum Sheet
Alloy”, paper 41.1., page 555, published in the 2006 Aluminium Proceedings.
Abstract
This paper presents a review of research conducted at the University of
Waterloo concerned with the application of aluminum alloy sheet and tube
in automotive structures and body panels. The research has focussed on
formability prediction and results using a range of damage-based
formulations. These models include continuum-level damage approaches
and, more recently, a so-called percolation damage approach intended to
capture microstructural heterogeneity effects on damage development.
This paper presents applications of these damage approaches to simulate
formability of experiments considering stretch flange panels. The
experiments consider drawbead effects associated with the bend/unbend
deformation as the material flows through the drawbead. Recent work on
simulating in situ X-ray tomography experiments that capture damage
evolution during tensile deformation will also be reviewed.
