From November 28 to 30, 2025, the 4th China–Belarus International Workshop on Computational Mechanics of Granular Materials was successfully held at the Institute of Mechanics, Chinese Academy of Sciences. Initiated by Dalian University of Technology and Belarusian State University, the workshop was hosted by the Institute of Mechanics, Chinese Academy of Sciences and the Institute of Process Engineering, Chinese Academy of Sciences, with co-organization from DBJI and the China-Belarus Belt and Road Joint Laboratory on Industrial Equipment and Instruments.

The opening ceremony was chaired by Professor Feng Chun from the Institute of Mechanics, Chinese Academy of Sciences, who served as the Chinese co-chair of the workshop. He introduced the history of the workshop and the arrangements for this session. Professor Huang Heji, Director of the Institute of Mechanics, Chinese Academy of Sciences, and Professor Michael Zhuravkov from Belarusian State University delivered opening remarks respectively, expressing expectations that the workshop would promote technical exchanges and cooperation between China and Belarus in geotechnical engineering, mineral resources and other related fields.

This workshop brought together more than 50 experts and scholars from top domestic universities and research institutions including Dalian University of Technology, Institute of Mechanics, Chinese Academy of Sciences, Institute of Process Engineering, Chinese Academy of Sciences, Beijing Institute of Technology, University of Science and Technology Beijing, Beijing Forestry University, Zhejiang University, Nanjing University and Xiangtan University, as well as renowned Belarusian universities and scientific research institutions such as Belarusian State University, Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus, and Joint Institute of Mechanical Engineering of the National Academy of Sciences of Belarus. Participants jointly discussed the latest progress and future development directions in the field of Granular Mechanics. Centering on four core themes—"Numerical Modeling and Granular System Coupling", "Granular Flow and Multiphase Flow", "Material Processing, Testing and Industrial Applications", and "Data-Driven Intelligent Design in Granular Mechanics"—the workshop arranged 20 wonderful thematic academic reports, which to a certain extent effectively reflected the current domestic and international research hotspots and latest advances.

During the workshop, Professor Ji Shunying, Secretary and Dean of DBJI, elaborated on the Discrete Element Method for Deformable Particles and Structures, demonstrating its innovative applications in complex material simulations. Professor Mikhael Zhuravkov from Belarusian State University shared the Coupled FEM-DEM Algorithm for deep mining geomechanical problems, providing a new technical approach for complex engineering simulations. Experts and scholars from Belarusian State University, including Mikhail Zhuravlev, Aleh Kanavalau, Dzianis Marmysh and Ivan Karpovich, systematically presented their series of research achievements in multi-scale coupling algorithms and complex engineering simulations, focusing on themes such as deep mining geomechanics, discrete element models for thin ice, brittle material processing simulation, and precipitation process modeling in chemical equipment. In addition, Researcher Andrei Chomy from the Heat and Mass Transfer Institute of the National Academy of Sciences of Belarus focused on the thermo-hydro-mechanical coupling modeling technology in process equipment. Researchers Iryna Tychynskaya and Uladzimir Basiniuk from the Joint Institute of Mechanical Engineering of the National Academy of Sciences of Belarus demonstrated the cutting-edge applications of computational mechanics in high-end manufacturing and microelectronics industries from the perspectives of precision processing of sup erhard materials and high dynamic load simulation.

The successful holding of this workshop has further consolidated the cooperation foundation between China and Belarus in the field of computational mechanics of geotechnical granular materials, and built a valuable exchange platform for research innovation and technological application in this field. Experts and scholars attending the workshop unanimously agreed that this in-depth exchange will effectively promote the collaborative development of both parties in relevant scientific research fields and lay a solid foundation for broader international cooperation in the future.
