在-10 ℃、4.5 × 10（-3）s（-1）的条件下，对柱状颗粒S2淡水冰的脆性压缩破坏进行了新的实验。结果和分析表明，在较高的约束条件下（σ（22）/σ（11）> 0.2），通过跨柱劈裂和从加载平面剥落发生终端失效，翼裂纹扩展和变形诱导薄板的欧拉屈曲的组合是该过程的基础。(C)2004 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
New experiments have been performed on the brittle compressive failure of columnar-grained, S2 fresh-water ice, proportionally loaded biaxially across the columns at -10 degreesC at 4.5 x 10(-3) s(-1). The results and analysis show that under higher confinement (sigma(22)/sigma(11) > 0.2) where terminal failure occurs via across-column cleavage and spalling out of the loading plane, a combination of wing crack growth and Euler buckling of deformation-induced thin plates underlies the process.
