Predictions of forming limit diagrams using a rate-sensitive crystal plasticity model

Effects of spatial grain orientation distribution and initial surface topography on sheet metal necking

“…Neale and Chater, 1980;Wu et al, 2003b;Stoughton and Zhu, 2004;Matin and Smith, 2005;Stoughton and Yoon, 2006;Vegter and Van der Boogaard, 2006) and crystal plasticity (see e.g. Zhou and Neale, 1995;Wu et al, 1997 andInal et al, 2005). Using the M-K approach, the predicted FLDs based on crystal plasticity were in good agreement with measured FLDs for rolled metal sheet (Wu et al, 1998;Knockaert et al, 2002).…”

Crystal plasticity-based forming limit prediction for non-cubic metals: Application to Mg alloy AZ31B

“…Additionally, mechanical twinning causes rapid texture evolution (Brown et al, 2005). A relatively simple, physically based approach to incorporate these effects into FLC prediction is to make use of polycrystal plasticity models as demonstrated previously for cubic metals (Zhou and Neale, 1995;Toth et al, 1996a). Although the use of crystal plasticity routines is more computationally demanding than closed form yield descriptions, it naturally accounts for the evolution of anisotropy due to texture evolution.…”
