Description
  • Comparison of accumulated damage field of coupled and uncoupled ductile damage models together with history of variables used in calibration process is presented in this paper. Using a non-linear damage accumulation in a local point of view, ductile failure criterion proposed by Xue is adopted and implemented into the Abaqus/Explicit via the user subroutine VUMAT for both types of models. Significant difference in localization between the coupled and uncoupled model is shown. The localization effect generally occurs when coupled models are used. One of the widespread practices to handle it is to use the non-local approach. In the other hand, we would not be able to predict a slant fracture without a certain degree of localization as shown in presented paper. Finally, the aluminum alloy 2024-T351 was examined.
