# 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

The modern form of application of fracture mechanics to concrete, which was first developed in Lund, differs from the conventional fracture mechanics in both these respects. All these applications of fracture mechanics require no field theory. Fracture mechanics applies whether the material is glass or rubber, and whether deformation is small or large. Rivlin and Thomas (1953) attributed this approach to Griffith (1921). The condition of small-scale fracture process zone.

A major spur to the development of fracture theory from 1940 onwards was the Jun 14, 2001 estimated the costs for failure due to fracture to be disintegrated in flight, provides a tragic but fascinating insight into the importance of fracture theory.

### Ninety years on, the influence of the Griffith criterion is still resonant in all aspects of fracture mechanics. To commemorate his seminal contribution, we organised a one‐day international workshop on fracture mechanics in March 2011 at the School of Engineering, the University of Liverpool, where Dr Griffith graduated with MEng and PhD.

Report. Browse more videos Applications of Fracture Mechanics Many applications of fracture mechanics are based on the equation c E σ2a Γ=β . Young’s modulus is usually known. Of the other four quantities, if three are known, the equation predicts the fourth. If you just read this equation, fracture mechanics sounds like a silly tautology.
