Abstract:Meso-scale modeling approach is helpful for understanding the mechanism of both global nonlinear behavior and local failure pattern of concrete materials and structures. As a typical multiphase composite material, concrete is composed of randomly-distributed coarse and fine aggregates, mortar, interfacial transition zone (ITZ) together with initial pores or defects. The meso-scale mechanical behavior of concrete usually exhibits nonlinear and stochastic characteristics. In this paper, the influence of both distribution and geometrical shape of aggregates, the existence of ITZ, and meshing approach on macro stress-strain relationship, damage evolution and the final failure pattern of concrete are studied systematically. The results indicate that the effect of meso-scale structure of concrete on the nonlinear and stochastic characteristics of macro stress-strain curves and failure patterns is different when the concrete specimen is under tension and compression loadings. Comparatively, the geometrical parameters of coarse and fine aggregates have limited effect on the macroscopic tensile strength, but obvious effect on the post-tension segment and the compressive macro stress-strain curve. Moreover, the damage evolution and failure pattern of concrete under uniaxial tensile and compression are sensitive to the meshing approach. The existence of ITZ affects the tensile and compressive strength of concrete significantly. The statistic characteristics of macro stress-strain curves under both tension and compression loadings from the multi-scale simulation is compared with that from experimental studies and the rationality of the meso-scale simulation approach is validated.

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.
