The Applied Materials Engineering Laboratory conducts research on materials processing. The fields of research can be broadly<br />
categorized into (A) metal processing, (B) polymer processing, and (C) applied materials processing. Research activities in these<br />
fields require a sound basic knowledge of viscoelastic dynamics, plastic dynamics, continuum dynamics, and plastic processing.<br />
Whether using metals or polymers, the major processing methods involve either exploiting high-strain-rate deformations or repeated<br />
deformations to plastically process metals in solid form in a mold, or heating materials above their melting point and exploiting the<br />
fluidity of the material to rapidly inject (cast) it under high pressure in a mold.<br />
In addition to basic experiments to elucidate the deformation and flow mechanisms, we apply finite element method (FEM) and<br />
difference method software (CAE analysis) to establish theories to assist engineering applications.<br />
The basic philosophy of this laboratory is to conduct "research on forming environmentally friendly materials (materials with low<br />
environmental burden)." While "environmentally friendly material" is difficult to define strictly, research topics are selected according<br />
to keywords such as "Recycling," "Functionality," and "Lightness," etc. However, industrial materials that match these keywords are<br />
not necessarily easy to process; in fact, most such materials are difficult to process. Consequently, our research topics center on<br />
materials which are significant from the material research viewpoint, but requires thorough research on the forming technologies for<br />
their industrial application.<br />
