Aug 18, 2020 at 19:42 comment added Botond That is probably not the best terminology, I just called it that for simplicity. In crystals you are looking for lattice defects (dislocations, for instance), whereas in amorphous materials such as glasses, they are called shear transformation zones (STZs). Strictly speaking, both dislocations and STZs are means of plasticity rather than cracking, but cracking usually happens where plasticity is prominent.
