of fracture mechanics, with applications to the earth-quake source seismology, including Cherepanov (1979), Rice (1980), Rudnicki (1980), Li (1987), Segall (1991), Scholz (2002), and Ben-Zion (2003), among others. This chapter reviews the essential aspects of fracture mechanics, with an emphasis on theoretical developments made over the last 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 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. J–Q Theory The J–Q Toughness Locus Single-parameter fracture mechanics theory assumes that toughness values obtained from laboratory specimens can be transferred to structural applications.
