Toughening Mechanisms in Composite Materials aims to provide a comprehensive and technically detailed coverage of composites and their toughening mechanisms. Unique in its direct and comprehensive approach, the book presents fundamental knowledge on composites’ toughening mechanisms as well as a comprehensive treatment of numerical methods. This volume summarizes the current state-of-the-art and presents the most recent research outcomes in the field. It details the development of each of the techniques, beginning with basic principles, and new concepts are illustrated with examples wherever possible.

Qing-Hua Qin

Dr. Qinghua Qin received his Bachelor of Engineering degree (1982) in Mechanical Engineering from Chang An University, China and obtained his Master of Science degree (1984) and PhD (1990) in applied mechanics from Huazhong University of Science and Technology (HUST), China. He joined the faculty of the Department of Mechanics at HUST from 1984 until he left for the University of Stuttgart (Germany) with the DAAD/K.C. Wong research fellowship in 1994. From 1995 to 1997, he returned to China as a postdoctoral associate at Tsinghua University. He was awarded the Queen Elizabeth II Fellowship from the Australian Research Council (ARC) in 1997 and a Professorial Fellowship of ARC in 2002 at The University of Sydney, Australia and stayed there till December 2003. He has been a Professor at the Research School of Engineering of the Australian National University, Australia from 2004 to 2021. He is now working at the Department of Engineering, Shenzhen MSU-BIT University, China. He is also appointed a guest professor at HUST since 2000 and Tianjin University since 2006.
