Caption: Principle strain state at fault tips in first stage of crack propagation. For a clear observation, this type of strain map is all magnified by 200 times compared with measurement value in this paper. (a) Strain field as wing crack growth at the upper tip; (b) strain field as wing crack growth at the lower tip.
