معرفی
Dr. Hongyang Cheng is an Assistant Professor at the University of Twente's Civil Engineering & Management Department, specializing in multi-scale modeling of granular materials and Bayesian uncertainty quantification for geotechnical applications. His work bridges physics-based and data-driven approaches, focusing on soil mechanics from quasi-static to dynamic behaviors, with applications in geohazard mitigation, laser sintering, and pharmaceutical powder processing.
Education:
- PhD in Multiscale characterization of geosynthetic-reinforced soil, Hiroshima University (2013–2016)
- Master's in Civil Engineering, Hiroshima University (2011–2013)
Dr. Cheng's research spans multi-scale modeling of granular materials, including Discrete Element Method (DEM) and Finite Element Method (FEM) integrations, and Bayesian uncertainty quantification frameworks like GrainLearning. His work addresses geotechnical challenges such as dike safety, offshore infrastructure resilience, and soil-structure interactions under extreme loading, utilizing machine learning surrogates to enhance computational efficiency.
Scientific awards include the Japanese Government Scholarship (2011), Best Student Paper at DEM2016, and IACMAG Excellence in 2022. He leads EU-funded projects like POSEIDON (offshore geohazards) and TUSAIL (upscaling particle systems), supervises postdocs/PhD students, and co-leads Working Group 1 for COST Action ON-DEM to promote open-source DEM tools.
Recent publications emphasize DEM's role in bio-cemented soils, vegetation effects on soil mechanics, and sintering kinetics. His teaching includes undergraduate courses on Soil Mechanics and graduate-level GeoRisk Management, integrating probability theory, stochastic modeling, and Python-based risk assessment tools.
