On the effects of temperature on the strength of H2SO 4-doped ice single crystals

Abstract

Previously, it was shown that the reduction in peak stress of single crystal ice at -20°C due to H2SO4, Δσ, could be described by Δσ = kC]/2, where C is the sulfuric acid concentration and k is a constant. Here we show that the strength reduction due to H2SO4 is more general and that the reduction is greater as the temperature decreases. Δσ was again found to be proportional to C1/2 at -10°C, but k at -10°C was significantly less than at -20°C.
