Programme Highlight

As global environmental changes intensify and urban populations and resources become increasingly concentrated, the risk of disasters from extreme weather events is rising. The Guangdong-Hong Kong-Macao Greater Bay Area, a crucial intersection of land and sea with dense underground infrastructure, is highly susceptible to climate change and prone to disasters. However, existing numerical approaches face challenges in simulating the intricate responses of soil due to the multiscale and multiphysics nature involved. This presentation introduces an advanced multiscale framework for modeling granular media in geotechnical engineering, considering multiple physical field couplings. The framework features an innovative continuous-discrete coupled multiscale computational method that bridges the gap between the microstructural characteristics of geotechnical materials and engineering practices. Additionally, a novel integration technique is introduced to extend this framework to the multiphysics domain, enhancing our ability to analyze and predict the complex behaviors of geotechnical materials under varying environmental conditions.

Speakers
Dr Weijian Liang is a Research Assistant Professor in the Department of Civil and Environmental Engineering at the Hong Kong Polytechnic University. He obtained his B.Eng. (Hons) in Theoretical and Applied Mechanics from Sun Yat-Sen University (SYSU) and his Ph.D. in Civil Engineering from the Hong Kong University of Science and Technology (HKUST). During his Ph.D. studies, he completed a half-year research exchange at UC Berkeley. His research interests focus on computational geomechanics, including multiscale and multiphysics modeling of granular materials, high-performance computing, meshless approaches (such as the material point method and discrete element method), and geotechnical analysis.
