Solid mechanics subarea
We study the mechanisms of deformation and fracture in materials based on solid mechanics and computational materials science. In particular, we focus on environmental embrittlement, including hydrogen embrittlement, as well as on the interactions between lattice defects such as dislocations, grain boundaries, and vacancies and various solute elements, using simulations at the atomic and electronic scales. By clarifying how these microscopic mechanisms affect macroscopic deformation behavior and strength and fracture properties, we seek to build a systematic framework of knowledge that bridges microscopic understanding and macroscopic mechanical properties, thereby contributing to strength assessment, improved reliability, and longer service life of mechanical and structural materials.
