Abstract

The 2021 5th International Conference on Mechanics, Mathematics and Applied Physics (ICMMAP 2021) was successfully held on July 23-25, 2021 in Guilin, China. ICMMAP 2021 is to bring together innovative academics and industrial experts in the field of mechanics, mathematics and applied physics to a common forum. The primary goal of the conference is to promote research and developmental activities in mechanics, mathematics and applied physics and another goal is to promote scientific information interchange between researchers, developers, engineers, students, and practitioners working all around the world. The conference will be held every year to make it an ideal platform for people to share views and experiences in mechanics, mathematics and applied physics and related areas.The conference model was divided into two sessions, including oral presentations and keynote speeches. In the first part, some scholars, whose submissions were selected as the excellent papers, were given 15 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 this conference, we were greatly honored to have three professors to serve as our Conference Chairman. There were over 120 experts and scholars in the area of Mechanics, Mathematics and Applied Physics representing different famous universities and institutes around the globe to attend our conference.During the conference, we were pleased to invite six distinguished experts to present their insightful speeches. The first keynote speaker, Prof. Boming Yu, from Huazhong University of Science and Technology. His main research interests include “fractal geometry theory and transport physics of porous media”. Prof. Guoping Zhao, from Sichuan Normal University. His research interests: Spintronics, theory in Skyrmions, spintronic information communication technology, magnetic recording, micromagnetics calculations and modeling in exchange spring, exchange bias and nanoclusters. And then we had Prof. Kuahai Yu, from School of Civil Engineering, Henan University of Science and Technology. Prof. Weiwei Zhang, from Mechanics Department of Taiyuan University of Science & Technology. In recent years, his research interests focus on the theoretical and experimental methods of micro defect detection in structures and materials, the history of mechanics and methodology. Prof. C W LIM, from City University of Hong Kong. Our finale keynote speaker, Prof. Zhi Zong, from Dalian University of Technology. Their insightful speeches had triggered heated discussion. Every participant praised this conference for disseminating useful and insightful knowledge.The participants of the conference were from most part of the world, with background of either academia or industry, even well-known enterprise. The success and prosperity of the conference is reflected high level of the papers received. The proceedings are a compilation of the accepted papers and represent an interesting outcome of the conference. This book covers 3 chapters: 1. Mechanics; 2. Mathematical Physics; 3. Physics.We would like to acknowledge all of those who supported ICMMAP 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. We sincerely hope that ICMMAP 2021 will be a forum for excellent discussions that will put forward new ideas and promote collaborative researches. We are sure that the proceedings will serve as an important research source of references and the knowledge, which will lead to not only scientific and engineering progress but also other new products and processes.The Committee of ICMMAP 2021List of Committee members are available in this pdf.
