Short summary
For the first time, digital image correlation was used to follow strain field development and evolution during micro-cracking, at the ductile-to-brittle transition in polycrystalline ice. Owing to the high-temperature conditions of the tests, dynamic recrystallization mechanisms (nucleation and sub-grain rotation) efficiently participate in the stress redistribution during and after crack opening, and even lead to local crack closure.
