š Hi, Iām Riichi Sugai!
Iām an Assistant Professor in Computational Safety Engineering
at the International Research Institute of Disaster Science (IRIDeS), Tohoku University.
My research focuses on developing the implicit Material Point Method (MPM) to evaluate soil flow and the resulting damage to structures through numerical simulation.
š Research Interests
- Improving implicit MPM for large-deformation problems in solids
- Developing stabilization methods to suppress volumetric locking and pressure oscillations in nearly incompressible hyperelastic and elastoplastic materials
- Simulating damage and fracture using phase-field fracture models
- High-performance computing (HPC)
š§© Current Work
Iām developing a mixed displacementāpressure formulation within the implicit MPM framework to suppress volumetric locking and pressure oscillations in elastoplastic materials. This formulation enables accurate deformation simulations of metals and geomaterials with reduced pressure oscillations. I plan to apply it to soil flow and structural failure simulations to contribute to the prediction and assessment of disaster-related phenomena.
