According to Kim et al. [8], the size effects can be divided as the feature/specimen size effect and the grain size effect.In general, the feature/specimen size can be referred to as the thickness of thin sheet metal in micro-forming. For size effects I, the grain size effect follows the Hall–Petch equation when the thickness is kept constant upon minimization [9], and the flow .
