Experimental Determination and Numerical Calculation of Fracture Viscosity Criterion (J-integral)

Experimental Determination and Numerical Calculation of Fracture Viscosity Criterion (J-integral)

The paper shows that it is necessary to accept energy J-integral criterion as a criterion of fracture viscosity under conditions when the zone of plasticity is rather large at crack top. Numerical modeling of fracture process has shown good convergence with experimental investigations of J-integral...
