Product miniaturization is an emerging trend for facilitating product usage, enabling unique
product functions to be implemented in micro-scaled geometries and features, and further …

The demand on micro-parts is significantly increasing in the last decade due to the trend of
product miniaturization. When the part size is scaled down to micro-scale, the billet material …

In micro-scaled plastic deformation process such as micro-forming, material grain size effect
is difficult to reveal and investigate using conventional material models. Finding a way to …

In this research, the interactive effect of grain and specimen sizes on the flow stress of sheet
metal in microforming is investigated via the tensile test of pure copper and numerical …

The size effect on material deformation behaviors are characterized by grain size, part
feature size, forming material size and interfacial condition. These factors have a close …

In micro-forming, when the billet material size is decreased to micro-scale, the mechanical
behaviors of material change and the so-called size effect occurs. The design and …

Microforming is one of the promising approaches to fabricating microparts for its high
productivity, low production cost and good mechanical properties. The material deformation …

By integrating the thermomechanically coupled simulation with the mathematically modeling
of microstructure evolution using Finite Element Method (FEM), the study of the dynamic …

In microforming, the workpiece size is in microscale and has only a few grains involved in a
deformation zone, leading to the deformation behaviors different from those in macroscale …

In micro-forming process, the prediction of deformation behavior is difficult as the
conventional material constitutive model is no longer valid when the part geometry is scaled …
