This book is the seventh volume of the proceedings for the symposium series on Fracture Mechanics,an annual conference devoted to the exchange of information among the universities, research institutions and industry sectors in China and abroad. FM2009 is held in Chengdu, Sichuan Province,from October 16 to October 20, 2009.
