授業の概要・目的 The lecture covers nonlinear continuum mechanics, dynamic three-phase analysis of ground and geotechnical structures, and fundamental behavior of saturated/unsaturated soil during geo-hazards. The lecture ranges from fundamental mechanics of granular materials to numerical simulation.
到達目標 Successful students will have the ability to initiate their own research work on geo-hazards based on the solid understanding of the mechanics of granular materials and numerical analysis.
