Considerable progress has been achieved in fractal characterization of the properties of crack surfaces in quasibrittle materials such as concrete, rock, ice, ceramics and composites. Recently, fractality of cracks or microcracks was proposed as the explanation of the observed size effect on the nominal strength of structures.

Tensile fracture of a single crack in first-year sea ice

Sep 28, 2018  1. Introduction. A fracture mechanics description of the tensile fracture of sea ice is sought. Sea ice mechanics ranges over a vast range in scales [1,2], with topics such as the laboratory-scale failure of ice under compression, structural-scale ice–structure interactions and mesoscale ridging, lead formation and ice rafting.The study of such topics has involved the analysis of subsets of ...

Reprinted From JOURNAL OF THE MECHANICAL BEHAVIOUR

The present paper deals with structures made of quasi brittle materials, such as concrete, rock, sea ice, toughened ceramics and composites. As a result of their heterogeneity and development of a large fracture process zone, these materials typically fail only after a large crack has grown in a stable manner.
