Growth and advancement in modern technologies and requirement of miniaturized parts in
various field of manufacturing has attracted several micro fabrication processes …

In manufacturing of metallic components, the size of the part plays an important role for the
process behaviour. This is due to so called size effects, which lead to changes in the …

The reduction of size for mechanical parts is more and more important in metal forming
processes. The optimisation of such processes needs more comprehensive use of …

The demand for accurate process design of microforming processes is increasing steadily
due to ongoing miniaturisation. Occurring size effects, however, prevent the transfer of …

Microforming is an effective method to manufacture small metal parts. However, macro
forming can not be transferred to microforming directly because of size effects. Flow stress …

Based on crystal plasticity theory and surface layer model, relation of flow stress to billet
dimension and grain size was built, and rationality of derived relation was verified with …

Micro-bending tests were performed to investigate effects of thickness and grain size on
material behavior in sheet metal forming. The rolling brass C2680 foil was selected as the …

With the miniaturization of parts, size effects occur in the micro-forming processes. To
investigate the effects of the specimen size on the flow stress, a series of upsetting …

Ongoing miniaturisation leads to increasing complexity of micro parts linked with
continuously decreasing development time. Hence, the demand for reliable material data …

The classical local continuum theory is not well adapted to represent the size effects in metal
forming processes because there is no dependence on length or size intrinsic parameters …
