Dr.Ā Hongyang ChengĀ is Assistant Professor of Geomechanics at the University of Twente. HeĀ obtained his PhD on "multi-scale characterization of geosynthetic-reinforced soils" at Hiroshima University in 2016. He subsequently joined the Multi-Scale Mechanics group of the University of Twente and worked on "wave propagation in granular media" and "concurrent multi-scale modeling" until 2020. For his PhD work, he received the best student paper award at the DEM7 conference andĀ a top downloaded paper award from Granular Matter. Dr. ChengĀ has been givingĀ invited lecturesĀ at the University of Pisa, Okayama UniversityĀ andĀ the Japanese Geotechnical Society, andĀ was the organizerā€Æandā€Æchair of the symposium ā€œOpen-Source Developmentā€ of the DEM8 conference in 2019.Ā Ā Dr. Cheng is currently guest-editing a special issue ofĀ Computers and GeotechnicsĀ "DEM for Geotechnics".

Dr. Cheng has worked extensively on the multi-scale and constitutive modeling of heterogeneous soils (e.g.,Ā GRS), Bayesian parameter estimation, and 3D micro-CT image analysis.Ā His research aims to understandĀ theĀ physical processes where the micro-mechanics is important and relevant length/time scalesĀ areĀ notĀ wellĀ defined. To this end, he develops multi-scale modeling and Bayesian inference tools to bridgeĀ geomechanicalĀ models at micro and macro scales.Ā His most recent work involves developingĀ a computational framework forĀ concurrentĀ multi-model simulations of granular matter, in all physical states.Ā 

Dr. Cheng has developed and coupled several open-source software packages, includingĀ YADE,Ā MercuryDPM,Ā OomphLib, andĀ LB3D, for solving geotechnics and geophysics problems, such as soil-geosynthetics interaction (FEM-DEM) and wave propagation in granular media (LBM-DEM). He has developed a Bayesian calibration software "GrainLearning" which has many users in the industry and academia. Dr. Cheng is the main developer of the coupledĀ MercuryDPM-OomphLibĀ code, with a vision to implement a unified multi-scale framework for modeling solid/fluid-like behavior of granular materials, incorporating state-of-the-art open-source codes from soil mechanics, fluid mechanics, and beyond.

Research profiles

In the Thermal and Fluid Engineering Department,Ā Dr. Cheng coordinated and gave lectures in three 5EC MSc courses, in which heĀ taught the dynamics of particle-fluid systemsĀ inĀ Multiphase Flows, soil elastoplasticity inĀ Granular Matter, and image analysis inĀ Advanced Programming in Engineering.

191158500 - APiE

201400194 - Granular Matter

201400300 - Multiphase Flows

In the Civil Engineering Department, he teaches an MSc courseĀ GeoRisk ManagementĀ (5EC). Students learnĀ how to use probability theory and stochastic modeling to integrate numerical models (e.g., FEM) and observation data within a probabilistic framework for risk assessment.Ā This multidisciplinary course covers several topics, including geomechanics, flow in porous media, finite element method, and stochastic modeling. Students practice the knowledge learned in the lectures via the final projectĀ "Dyke Risk'', by implementing a small Matlab soler for probability-based dike stability assessment.
