WebJan 21, 2024 · This phenomenon, known as elastic crack blunting, is peculiar of rubber-like polymers and soft biological tissues, such as skin, vessel walls, and tendons. With this work, we aim to provide a discussion on crack-tip blunting and its implications in terms of tearing resistance and flaw tolerance of soft elastic materials.

Effect of Crack Blunting on Subsequent Crack Propagation
WebApr 1, 1980 · A quantitative model has been developed to account for the degree of blunting that occurs at crack tips in epoxy materials prior to the onset of crack propagation. This mechanism controls the... WebMay 31, 1999 · The analysis reveals that the favorability of crack propagation versus dislocation emission depends upon the bluntness of the crack tip. One implication is that a crack may initially emit dislocations only to reinitiate cleavage upon reaching a sufficiently blunted tip geometry. The present framework is used to classify crystals as… WebJun 8, 2003 · We propose two mechanisms by which crack growth can occur in such blunted regions.
