On December 22-23, 2023, the State Key Laboratory for Nonlinear Mechanics (LNM) of Institute of Mechanics (IMech), Chinese Academy of Sciences (CAS) held its Academic Annual Conference in Beijing. The event was attended by Prof. Wei Zhixiang, Deputy Director of Bureau of Frontier Science and Education, CAS; Zhang Junping, Director of the Department of Astronomic and Mechanics of the Bureau; Chen Hudong, Member of the National Academy of Engineering, USA; Prof. Wu Heng'an, Dean of the School of Engineering Science at the University of Science and Technology of China; Prof. Li Jiachun, Member of National Academy of Sciences, China; Prof. He Guowei, Member of National Academy of Sciences, China and Academic Director of IMech; Prof. Luo Xisheng, Director of the IMech; Ye Haihua, Secretary of the CDI, IMech. Over 220 researchers and students from Peking University, Tsinghua University, University of the Chinese Academy of Sciences, University of Science and Technology of China, participated in this conference.

The opening ceremony was organized by Prof. Jiang Minqiang, Deputy Director of LNM. Important speeches were delivered by Prof. Wei Zhixiang, Deputy Director of Bureau of Frontier Science and Education, CAS, and by Prof. Luo Xisheng, and Prof. He Guowei as the Director and the Academic Director of IMech. They acknowledged the LNM's achievements in the last year, not only on the reform of State Key Laboratory but also the advances in scientific research and encourage all members of the laboratory for a persistent continuation. They also encouraged the laboratory to further strengthen its organization and teamworking culture, by upholding its excellent traditions established by the scientists of older generations. They pointed out that the role of a state key laboratory is, on one hand, to make significant advancement in scientific research, and one the other hand, to fulfill the demand of the nation. After the speeches, Prof. Wei Yujie, Director of LNM, presented the annual work report of 2023 and reviewed the 28-year history of LNM as the State Key Laboratory, dated back to 1995. The report presented the current status, and future development plans of LNM. A detailed summary of the key scientific advancements made in 2023 is also included.

The remainder of the conference consists of invited 23 talks, presented by guests from the United States, Germany, Hong Kong, and various domestic universities and institutes in mainland China. The topics covered the major scientific issues of the nonlinear mechanics together with cutting-edge interdisciplinary directions, including fundamental theories of turbulence, industrial software of computational fluid dynamics, mechanical behavior of advanced materials, nonlinear fluid-structure interaction, electro-mechanical coupling, and key mechanical challenges in national projects and natural environments, etc.
