| Abstract |
The effectiveness of the improved Ritchie-Knott-Rice failure criterion ((4δt, σ22c) local fractures criterion) for converting the minimum fracture toughness value of different conditions has been confirmed. In this paper, the traditional Minami calibration approach is improved, and an improved method of Beremin models parameter calibration is obtained. This improved method is based on the minimum toughness value obtained from the above criteria, and the non-dimensional deformation limit value (M) proposed to ensure the crack tip's constraint. With this improved method, the model parameters' calibration process only requires the material parameters obtained from the tensile test and the three-dimensional finite element analysis based on these material parameters. In this process, a large number of complex fracture toughness tests are not required. Finally, fracture toughness data onto 16MnDR steel and A515-70 steel was used to verify this method. The outcomes indicate that it helps predict the failure probability of the calibrated result, demonstrating this method's feasibility. |
