Fracture Mechanics Applied To Ice Ih

Presented by: 
John Dempsey Clarkson University, Aalto University
Friday 8th December 2017 - 14:30 to 15:30
INI Seminar Room 1
The initial reluctance to adopt the fracture mechanics approach in ice mechanics and ice dynamics will be examined. The fundamentals of fracture mechanics and different fracture criteria will be reviewed. The relationship between models that idealize the crack-tip as a singular stress field and those that include a cohesive zone will be explored. Experimental values of material parameters determined in the laboratory and in the field will be examined. Time dependent and material effects on crack growth initiation and during crack propagation will be discussed. The limitations of fracture mechanics will be explored.
