Research Contents

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