The 2021 International Conference on Advanced Materials and Mechatronics (ICAMM 2021) was planned to be held on October 30 - November 1, 2021 in Kunming, China. Currently, the entire world is struggling against the virulent pandemic COVID-19. Unfortunately, each of us is affected, either overtly or covertly. Our conference, 2021 International Conference on Advanced Materials and Mechatronics (ICAMM 2021) was not an exception. The ICAMM 2021 was changed to be held online through Zoom software. This approach not only reduces people gathering, but also meets their communication needs.Nowadays, the research and development level and industrialization scale of advanced materials have become an important symbol to measure the economic and social development, scientific and technological progress and national defense strength of a country or region. Compared with the traditional mechanical manufacturing, the composite mechanical and electronic engineering and its technology with the introduction of artificial intelligence technology have a greater application prospect, and can meet the needs of increasingly complex industrial production and manufacturing in the era of highly developed industrial capacity. Advanced materials and mechanical and electronic mutual integration, mutual promotion, the penetration of relevant research and results affect the development of various fields in China, which is of great significance to accelerate China’s social upgrading and transformation and seize the commanding heights of a new round of scientific and technological revolution. The purpose of the conference is to build a bridge of communication for experts, scholars and personnel from all walks of life in the field of materials and electromechanics, and to help and promote the intersection and integration of different disciplines.We were greatly honored to have invited Prof.Wenhui Ma, Kunming University of Science and Technology, China and Prof. Yuanchang Zhong, Chongqing University, China to serve as our Conference Chairman. There were over 105 participants attended the meeting.During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In the second part, we invited three professors as our keynote speakers. The first one, Prof. Weidong Zhu, from University of Maryland. His research spans the fields of dynamics, vibration, control, applied mechanics, structural health monitoring, metamaterials, and wind energy, and involves analytical development, numerical simulation, experimental validation, and industrial application. Prof. Junxi Bi, Inner Mongolia University of Technology as our second keynote speaker. Prof. Xinyong Li, from Dalian University of Technology. His mainly research interests: energy catalysis, nano catalysis, green catalysis, nano science and engineering, chemistry and biosensor. Their insightful speeches had triggered heated discussion in the third session of the conference. Every participant praised this conference for disseminating useful and insightful knowledge.The proceedings of ICAMM 2021 span over 6 topical tracks, that include: Mechanics of materials, Structural mechanics, Mechanics, dynamics and its applications, Irradiation electronics, Optical/electronic/magnetic materials and other related fields. All the papers have been through rigorous review and process to meet the requirements of International publication standard.We would like to acknowledge all of those who have supported ICAMM 2021. Each individual and institutional help were very important for the success of this conference. Especially we would like to thank the organizing committee for their valuable advices in the organization and helpful peer review of the papers.The Committee of ICAMM 2021List of Committee member are available in this pdf.
