Abstract

On the basis of the analysis of the stability of an interacting system of straight edge cracks it is shown that when the fracture strength of the ice is taken to be nonzero, there exists a minimum spacing for waterfree crevasses (about 6-8m). This spacing is, in general, much larger than the minimum crack spacing (about 1/3m) needed in order to be able to attain the critical value of the stress intensity factor, and therefore, in general, the minimum spacing of the water-free crevasses is dictated by the stability consideration, rather than by the consideration of the stresss alone. -from Authors
