Assist. Prof. Hiroyuki Kyokawa had a presentation in “2nd International Conference on Energy Geotechnics” in La Jolla, San Diego. The presentation title was “Constitutive model describing the hydro-mechanical behaviors of compacted bentonite clay based on the crystal surface phenomena”. That conference has been postponed from Sep. 2020 due to COVID-19, and it was held in person. Nothing beats conference face-to-face!!
