Do cracks reduce thermal ice stresses? / Lennart A. Fransson.

Title: Do cracks reduce thermal ice stresses? / Lennart A. Fransson.
Author(s): Fransson, Lennart A.
Date: 1991.
Publisher: Berlin: Springer
In: Ice-Structure Interaction. IUTAM/IAHR Symposium, St. John's, Newfoundland Canada 1989. (1991.),
Abstract: Discusses different effects of cracks on stress-strain relationship, based on field measurements of ice stresses in river. Nonlinear continuum model is used to analyze stress measurements; this model treats ice as uncracked continuum on average. Simplified relationship for cracked ice is also proposed, in which ability to build up compressive stresses increases linearly with stress level and creep rate is proportional to square of stress level. Possible that gradual accumulation of large horizontal ice loads depends on cementation of cracks formed during periods of cold temperatures. In most cases cold ice appears to be cracked. These cracks may explain why most reservoir dams and bridge piers in nordic countries remain undamaged.
