研究室紹介
Professor Han, Heung Nam's research lab specializes in computational materials science and mechanical metallurgy, focusing on the fundamental mechanisms of deformation in metallic materials under coupled thermal, mechanical, and electrical fields. The lab integrates first-principles calculations, finite element modeling, and experimental validation to investigate phenomena such as electroplasticity, hot tearing in steel casting, and the mechanical behavior of solidifying alloys. A key strength lies in the development of advanced simulation frameworks—particularly combining artificial neural networks with finite element analysis—for extracting material properties from indentation tests. The lab also explores microstructural effects, such as grain boundary behavior and solute segregation, on macroscopic deformation and failure.

15Electroplastic phenomenon has been demonstrated by that the elongation increases remarkably during deformation under electric current without a significant elevation of temperature due to Joule heating. Since the 1960s, the electroplasticity has been actively investigated; however, an exact explanation of the mechanism has been lacking. In this study, the origin of electroplasticity in metallic materials is elucidated based on first principle calculation, finite element simulation and experiment
