报告人简介

Jiye Chen is Chair/Prof in Mechanics of Structural Composites, and the Leader of research group of Materials, Structure and Geotechnics in the University of Portsmouth, UK. He is member in European Mechanics Society, Scientific Committee of International Conferences on Mechanics of Composites, and Composite Structures, Member of the Research Centre for Materials and Structures of Defense Science and Technology Laboratory, UK. He is guest editor for two international journals: Composite Structures and Engineering Fracture Mechanics. His research areas include: Nonlinear Computational Damage Mechanics, Mechanics of Composite Materials, and AI image technologies for non-destructive multiscale damage detection and surveying, and additively manufacturing continuous fibre reinforced composites. He published over 80 international peer reviewed journal and conference papers, and book chapters. He owns two international patent technologies. He is regularly invited to chair sessions in International Conferences on Mechanics of Composites, and Composite Structures, to give keynote speeches, and to give guest lectures to several international academic institutes in the last two decades.  


报告内容简介

The essential fracture mechanism in engineering materials and structures is damage initiation, accumulation, and evolution under service loading conditions. To improve material resilience to fracture, fatigue and impact damage, and to optimise the performance of critical structural components, it is required to predict material state changes from elastic, plastic, damage and final fracture. This online lecture will introduce recent development of Nonlinear Computational Damage Mechanics and its applications in predicting detailed material failure mechanism and optimising mechanical behavior. This online lecture will briefly introduce history of fracture mechanics, linear computational fracture approaches and nonlinear computational fracture approaches. This lecture will focus on one of nonlinear computational damage mechanics approaches, extended cohesive damage model (ECDM). Examples of applications of the ECDM will be given to show its powerful functions in predicting multicrack propagation in engineering materials and structural components, and achievements in optimising the best mechanical performance of materials or structural components. This lecture will also present the ECDM as a robust tool in studying multicrack growth in a wide range of engineering materials and structures.
