“…The fabric variations with depth in the sheet [Cole et al, 1995] show the development of a strong preferred c axis orientation. The cores were transported to the U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) and subjected to a series of creep and cyclic loading experiments [Cole, 1993;Cole and Durell, 1995a].…”

Abstract. Characteristics such as brine and gas porosity and crystallographic features can have a profound impact on the mechanical properties of first-year sea ice. These characteristics vary spatially and temporally, and it is important in the development of constitutive models to address their variability in physically meaningful terms. A program of laboratory experiments on field cores of first-year sea ice has been conducted to aid in the development of such models. A thorough assessment of the bulk physical properties and microstructural characteristics of the ice has been carried out in conjunction with a detailed set of cyclic loading and creep experiments. Methodology was developed to calculate an orientation factor that determines the average shear stress resolved on the basal planes, given the background normal stress. Examination of the constitutive behavior using laboratory cyclic loading and constant load creep experiments revealed that the elastic, anelastic (time-dependent recoverable), and viscous strains varied systematically with the orientation factor. The observations also indicate significant brine porosity effects on the elastic, anelastic, and viscous components of strain. A recently developed constitutive model was expanded to include a frequency-and orientation-dependent viscous straining term, and the model predictions agreed well with the experimental observation.

“…The analysis is identical to the case of fluid-filled pores but, here, the modulus of the dry or empty inclusion is zero. For both saline and non-saline low porosity ice (f < 0.1), a decrease in effective Young's modulus has been observed (Cole 1995;Cole and Durell 1995) and found to follow the form: E(GPa) ¼ 10.0-35.1f (Langleben and Pounder 1963). It has been posited that in small icy satellites (<1000 km in radius), modest self-gravitation further decreases effective modulus, which should enhance the tidal evolution of binary asteroids (Goldreich and Sari 2009).…”

“…More recently, the significant bulk of work on dissipation in both laboratory grown and natural sea ice to date has been conducted by David Cole and various coworkers (e.g. Cole 1995Cole , 2001Cole et al 1998;Durell 1995, 2001).

“…This model was introduced by Cole (1995) in order to quantify the experimental observations of attenuation in saline ice and isolate the relaxation due to dislocation motion (Cole and Durell 1995). As such, it is the only model developed specifically to characterize the response of ice.…”

A viscoelastic fictitious crack model has been applied in this paper to the analysis of large‐scale in situ sea ice tests. By matching the experimental response, a stress‐separation curve has been derived for the in situ response of sea ice. The importance of including time dependent deformations in sea ice fracture models is illustrated. The limitations of the fictitious crack model in reproducing the ‘stick‐slip’ crack growth typically observed in sea ice are revealed. Copyright © 1999 John Wiley & Sons, Ltd.
