Also, experiments on glass fibers that Griffith himself conducted suggested that the fracture stress increases as the fiber diameter decreases.
2.
The work-hardened steel bar fractures when the applied stress exceeds the usual fracture stress and the strain exceeds usual fracture strain.
3.
Such structures show good mechanical properties ( elastic modulus 450 GPa, fracture strain 3.7 %, fracture stress 17 GPa ) and can be applied as reinforcement of ceramics or in micromechanical systems.
4.
Assuming " E " = 62 GPa and " ? " = 1 J / m 2 gives excellent agreement of Griffith's predicted fracture stress with experimental results for glass.
5.
Had a great start to the season, making the final in Brisbane, winning in Pattaya and feeling very good about my game, but unfortunately, suffered a fracture stress . . . that kept me away from the tracks for two months . " However, she said that playing in the Olympics at Wimbledon, where she reached the third round, was a " special moment ".
