Abstract:To reveal the physical mechanism of strain rate effect of concrete subjected to compression with different loading speeds, parametric analysis on the nonlinear behavior of concrete was performed using mesoscale finite element (FE) modeling approach in this study. The effects of geometrical shape and distribution pattern of aggregates, interfacial transition zone (ITZ), loading approach, viscosity parameters, element meshing techniques and other mesoscopic influence factors on the failure pattern, compressive stress-strain relationship and dynamic increase factor (DIF) of concrete cubes were systematically investigated using explicit and implicit dynamic analysis respectively. The numerical findings indicate that the DIF is mainly induced by the inertial effect of the concrete specimen under dynamic loading and the strength enhancement should be considered in material definition. Besides, it has proved that the DIF is related to the variation of distribution pattern and geometrical shape of aggregates, and mesostructure randomness of concrete needs to be explicitly modeled in mesoscale numerical analysis. In addition, the viscosity parameter imposes significant influences on the convergence issues and the accuracy of numerical results from implicit dynamic analysis. More importantly, the variation trend of DIF is sensitive to the specific value of viscosity parameter. Key issues with regard to mesoscopic analysis of concrete specimen under dynamic loading were systematically investigated in this study and the research findings can provide valuable references for mesoscale modeling of concrete components subjected to dynamic loading with different strain rates.

Dr. Bin Xu is currently the Minjiang Scholar Professor of Civil Engineering, a professorship appointed by Fujian Provincial Government, at Huaqiao University, Xiamen, China. He currently is the Director and Founder of the Key Laboratory for Intelligent Infrastructure and Monitoring (IIM) of Fujian Province, and the Director and Founder of the International Centre for Safety and Sustainability of Civil Engineering at Huaqiao University.
Before joining Huaqiao University, he was a Lotus Scholar Professor of Civil Engineering (a professorship appointed by Fujian Provincial Government) at Hunan University from 2005 to 2016 and was also the associate dean of the College of Civil Engineering at Hunan University from 2010 to 2016. He was also the Director of the Hunan Provincial Key Lab on Damage Prognosis for Engineering Structures from 2015 to 2016 at Hunan University. He taught and carried out research at the Lyles School of Civil Engineering at Purdue University as a Curtis Visiting Professor appointed by Purdue University in 2014-2015 academic year. He had been invited and financially support by European Commission to work at Sapienza University of Roma in 2010 and hired by University of Western Australia as a Gledden Visiting Senior Fellow from 2007 to 2008. Before starting working in China in 2005, he worked at University of Missouri-Rolla in US as a Post-Doc from 2003 to 2005 and at Ibaraki University in Japan as a Japan Society for the Promotion of Science (JSPS) postdoctoral fellow from 2001 to 2003.
He has been the supervisor of 7 Ph.D., 1 Post-Doc, 4 international visiting students and over 60 MS students. All of his PhD students are working at universities. Dr. Xu has committed to securing competitive external funds to support programs, research, and labs. He has been the PI and Co-PI of 14 competitive government funded research projects including a China- European Commission international collaborative research project, an international collaborative research project between National Natural Science Foundation of China (NSFC) and National Natural Science Foundation (NSF) of US, and a number of NSFC research projects. He is also the recipient of Grant-in-aid of 7 talent programs sponsored by China Ministry of Education (CMoE) and other government agencies.
He also serves on various academic societies as Editor-in-Chief, Executive Editor, Associate Editor, Guest Editor or editorial board member for international journals and professional committees as Standing Committee Member, Executive Member or Committee Members.
