Crushing strength of lake ice
Butkovich, Theodore R.
Tests were made to determine the effects of size of prismatic specimens, cross section, ratio of overall length to length of side of square section, types of ice, both natural clear ice and snow ice, orientation of c-axis, and size of candle. Rough-cut specimens were crushed in a 120, 000 lb capacity press. The results of the tests show that: ( 1) Larger-grained clear ice is stronger in compression. (2) Ice is stronger parallel to the ice sheet than normal to it. (3) Specimens of smaller cross-section have higher crushing strength. (4) Prisms with lower ratios of length to width are stronger. No effect of c-axis orientation was detected.
