Existing approaches for collapse modeling
Macro-model FEM
� Fracture using spring elements / critical plastic strain -> “delete element”
� Kanvinde (2003), Rodgers and Mahin (2006), Lee and Foutch (2004)
� Khandelwal et al. (2008), Fu (2009), Szyniszewski (2012)
� Concentrated plasticity: Kaewkulchai and Williamson (2004)
