研究室紹介
Professor Hyeong-Joon Jang's research lab specializes in computational materials science and micromechanics, focusing on the deformation behavior and microstructure evolution of metallic materials under complex loading conditions. The lab employs advanced numerical methods such as crystal plasticity finite element modeling (CPFEM) to investigate subgrain texture development, dislocation dynamics, and misorientation distribution effects in face-centered cubic (FCC) metals. A key research direction involves understanding how local crystallographic interactions at the subgrain level influence macroscopic mechanical properties through tailored microstructural design.

2We applied the crystal plasticity finite element method (CPFEM) based on a rate sensitivity model to examine the subgrain texture evolution of FCC metals under shear deformation. We used two kinds of microstructure models with the same orientation distribution function (ODF) but different spatial arrangements or misorientation distributions (MDs). One contained a great high frequency around low misorientation angles and the other a great high frequency near high misorientation angles. Different
