A comparative analysis of several nonlocal fracture criteria [PDF]

open access: yes, 1998
Comparative analysis has been carried out for three nonlocal fracture criteria (NLFC) in application to plane problems: the average stress fracture criterion (ASFC), the minimum stress fracture criterion (MSFC) and the fictitious crack fracture criterion

SWIIFT v0.10: a numerical model of wave-induced sea ice breakup with an energy criterion [PDF]

open access: yesGeoscientific Model Development
The wave-induced breakup of sea ice contributes to the formation of the marginal ice zone in the polar oceans. Understanding how waves fragment the ice cover into individual ice floes is thus instrumental for accurate numerical simulations of the sea ice
