Abstract

<jats:title>Abstract</jats:title> Previously, it was shown that the reduction in peak stress of single crystal ice at −20°C due to H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub>, Δ<jats:italic>σ</jats:italic>, could be described by Δ<jats:italic>σ</jats:italic> = <jats:italic>kC</jats:italic> <jats:sup>1/2</jats:sup>, where <jats:italic>C</jats:italic> is the sulfuric acid concentration and <jats:italic>k</jats:italic> is a constant. Here we show that the strength reduction due to H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub> is more general and that the reduction is greater as the temperature decreases. Δ<jats:italic>σ</jats:italic> was again found to be proportional to <jats:italic>C</jats:italic> <jats:sup>1/2</jats:sup> at −10°C, but <jats:italic>k</jats:italic> at −10°C was significantly less than at −20°C.
