The compressive failure of ice is an important consideration in the design of engineered structures for use in ice-infested waters, in some cases limiting the forces applied. This paper presents a short overview of the brittle compressive failure of terrestrial ice (i.e. ice I_h) and th transition from brittle-to-ductile behavior. Frictional crack sliding, as envisaged by McClintock and Wlash in 1963, and wing cracking appear to play major roles.
