摘要：
The Luders deformation process in hot-rolled steel was observed in situ using digital image correlation (DIC). The outcomes are as follows: (1) all of the variables depicting the Luders deformation can be measured simultaneously via DIC; (2) a moving band can be identified and measured in the strain rate field.
