“…As the ice does not behave in the same way under tensile or compressive stresses (Schulson and Duval, 2009), we believe this criterion is not suited to describe ice fracturing processes. The Hayhurst criterion (Hayhurst, 1972;Gagliardini et al, 2013a), which involves the maximum principal stress, cryostatic pressure and the von Misès stress invariant, was designed to describe creep damage in ductile materials and allows for damage under uniaxial compression. However, as we want to describe crevasse opening under tension only, we believe that this criterion is not suitable for this work.…”

“…Future research needs to be carried out to identify=develop a set of damage constitutive equations to accurately model the creep damage behaviour of the material. The traditional creep damage constitutive equations, such as single damage variable equations developed by Kachanov [16], Hayhurst [17], etc., will be considered.…”

“…Vauriomekaniikkaan perustuva lähestymistapa muodostaa hyvän lähtökohdan, ja sitä on sovellettu useissa tutkimuksissa [1,4,11,12,13,25,27,34]. Tässä artikkelissa tarkastellaan etupäässä sekundääristä ja tertiäärivaiheen virumaa, joten yksinkertaisin mahdollinen sisäisten muuttujien joukko koostuu vain yhdestä skalaari-vauriomuuttujasta.…”
