Analysis of micro/mesoscale sheet forming process with uniform size dependent material constitutive model

Based on this uniform size dependent constitutive model, numerical simulation models of micro/mesosheet forming process are established to investigate the influence of the size effects. The results show that there is obvious difference in the punch force and Mises stress distribution between the results with consideration of size effects and that without size effects. Therefore, the size effects should be considered in micro/mesoforming process design.
