Extended Data Fig. 2: Comparison of flow-law predictions and experimental measurements at low strain.
From: Flow laws for ice constrained by 70 years of laboratory experiments
Measured stresses are plotted against measured strain rates with symbols coloured by discrepancy, \(\log ({\Delta }_{{\rm{P}}-{\rm{M}}})\), between flow law and measurement (Methods), respectively, at low strain (1–2%). a, b, and c, Comparisons with one-component flow laws: Glen flow law (a), GSI flow law (b), and GSS flow law (c). d and e, Comparisons with two-component flow laws: Goldsby–Kohlstedt flow law (d) and a two-component flow law with parameters evaluated in this study (e). f, Comparisons with the three-component flow law. Pale shades signify a close agreement between flow-law predictions and measurements, whereas darker shades highlight deviations between the two. Shapes differentiate experiments conducted by various research groups using similar experimental approaches. The five-point star represents Glen’s group6,7. The square represents Duval’s group17. The circle represents Jacka’s group21,22,23,24,25,28. The six-point star represents Goldsby–Kohlstedt’s group27. The left-point triangle represents Piazolo’s group29. The up-point triangle represents Montagnat’s group30. The down-point triangle represents Mellor’s group18,19. The right-point triangle represents Vaughan’s group31. The diamond represents Goldsby–Prior–Durham’s group20,32,33,34,35,36,37,38. The use of the Glen flow law16 with calibrated parameters42 is shortened as Glen‒Kuiper. The use of the Goldsby-Kohlstedt flow law8 with calibrated parameters42 is shortened as GK‒Kuiper.
