  • Numerical determination of J-R curve using void model
    Laš, Vladislav ; Očenášek, Jan ; Vacek, Vlastimil
    The paper presents the determination of the J-R curve for an aluminium alloy. J-integral value is determined by numerical simulation of the test prescribed in ASTM E 1820-01. The crack growth ... [Delta]a corresponding to the load increment is determined numerically. The Complete Gurson Model (CGM) based upon void models is adopted as a constitutive relation. This model describes the nucleation, growth and the coalescence of voids and it considers the constraint effect as well. The advantage of this approach is when compared with the standard experimental determination of the J-R curve that the number of experiments is reasonably lower in this case since only the experiments forthe determination of the CGM parameters are needed. These experiments require much less effort and are less time demanding. Numerical simulations for the determination of the J-R curve were performed for the CT specimen. The finite element method (FEM) code ABAQUS was used for the computation. A subroutine including the CGM was implemented into the code. Static loading and room temperature were assumed in all simulations.
