The 2026 National Conference on Solid Mechanics was successfully held in Tianjin from August 21 to 24. Organized by the Solid Mechanics Committee of the Chinese Society of Theoretical and Applied Mechanics, the conference focused on the theme "Frontiers and Challenges in Solid Mechanics" and featured various academic exchange formats, including plenary sessions, specialized symposia, and poster presentations. With one main session and 29 sub-sessions, the event brought together over 3,000 participants, including more than 20 academicians and experts in solid mechanics, making it the largest comprehensive academic conference in China's mechanics community in 2026.

On August 23, during the special session MS28 titled "Mechanical Problems in Marine and Ship Engineering," I delivered an invited lecture entitled "Digital Twin Method for Simulation Analysis and State Inversion of Offshore Structures under Complex Marine Environments." The presentation discussed simulation analysis, state inversion, and digital twin methodologies for offshore structures in complex marine conditions. It introduced a research framework integrating environmental data, structural models, and monitoring information to analyze structural mechanical states, and shared insights on applying digital twins for intelligent perception and safe operation and maintenance of marine engineering structures. Dr. Jiang Chunhao, a Ph.D. student from our research group, presented an oral report titled "Virtual Sensing Method for Offshore Wind Turbine Structures Based on Subspace Spectral Graph Networks" and also displayed related research findings through a poster presentation. Participation in this conference strengthened academic exchanges with domestic peers and further broadened our research perspectives in digital twins, intelligent sensing, and safety operations for marine engineering structures.

Note: The Chinese Society of Theoretical and Applied Mechanics, established in February 1957, is a national academic organization under the China Association for Science and Technology, dedicated to advancing the development of mechanics and promoting academic communication.

The paper "A digital twin-based framework for simulation and monitoring analysis of floating wind turbine structures," published by the research group, has surpassed 100 citations on Google Scholar. It is worth noting that as of this year alone, this article has been cited 38 times.

The research has attracted significant attention from the academic community, primarily because it addresses key technical challenges in offshore wind power development. To tackle the difficulties of managing multi-source and heterogeneous data in the design and operation of floating wind turbines, the study proposes a unified framework based on digital twin technology. By leveraging three-dimensional models to achieve real-time synchronization and inversion of sensor data, it effectively resolves challenges related to data integration and simulation analysis throughout the turbine's entire lifecycle. Meanwhile, the proposed technical system features a clear pathway, has been validated through engineering practice, and offers strong methodological reference value and broad applicability across various scenarios.

The research group has also published several papers related to digital twin technology. Among them, the paper "The Application and Development of Digital Twin in the Marine Domain" focuses on digital twin technology for ship applications, providing a detailed discussion on concepts, application frameworks, key technologies, and future development in the field of marine digital twins, and has been cited 9 times on Google Scholar. The paper "Real-time Monitoring and Analysis for Digital Twin of Floating Wind Turbine" proposes a monitoring and analysis framework suitable for floating wind turbine digital twins, which has been cited 3 times on Google Scholar. Meanwhile, "Research Prospect of BIM-Based Information Technologies for Engineering Management" explores the future development of digital twins in engineering from the perspective of building information technology, and has been cited 43 times on China National Knowledge Infrastructure (CNKI).

The paper "Nonlinear Vortex-Induced Vibrations of Fluid-Conveying Pipes with Gravity-Induced Slight Initial Curvature" has been published in the journal Materials.

Vortex-induced vibration (VIV) is one of the primary causes of fatigue failure in subsea pipelines and has attracted significant attention from researchers in recent years. Most existing studies have focused on idealized straight pipes, while the effect of slight bending caused by gravity in free-span fluid-conveying pipes has been less explored. This paper establishes a theoretical model incorporating axial tension effects and gravity-induced initial slight curvature. The governing equations were derived based on Hamilton's principle, and the fluid-structure interaction was modeled using the Van der Pol equation. The vibration response was solved using the Galerkin method combined with the Runge-Kutta method. The accuracy of the model was verified by comparing response curves and bifurcation diagrams with those from previous literature. The study revealed that gravity-induced slight curvature reduces the VIV response mode; the static deformation of the pipe decreases with increasing axial tension but increases with higher internal flow velocity. At the same external flow velocity, the initial deformation lowers the dominant frequency and transforms the vibration response from quasi-periodic to periodic motion.
