(8) When such energy is really sufficient to produce the new fracture surface, then the real crack extension can occur: J, = J,c (9) in which J,c is coincident with ~,c in the case of linear material. The integral J, can be defined again for an elastic-plastic material following Fracture mechanics has now evolved into a mature discipline of science and engineering and has dramatically changed our understanding of the behaviour of engineering materials. One of the important impacts of fracture mechanics is the establishment of a new design philosophy: damage tolerance design methodology, which has now become the industry standard in aircraft design. To more effectively quantify constraint effects on crack-tip fields and fracture resistances in ductile materials, a modification of the J-Q theory (O'Dowd and Shih, 1991) is proposed by introducing a parameter Q*. Results show that Q* is a load-independent constraint parameter under LSY or fully plastic deformation. The validity of J-Q* description has been demonstrated by three applications Fracture Mechanics of Concrete Structures: From Theory to Applications : Report of the Technical Committee 90-Fma Fracture Mechanics to Concrete-App: Amazon.it: Elfgren, L.: Libri in altre lingue Fracture mechanics concepts other than the LEFM approach are therefore necessary to address structural integrity analysis of components that are ductile.
