Material Testing of PH13-8MO H950 Steel for Xue-Wierzbicki Fracture Criterion Determination
- Sandia National Laboratories (SNL), Albuquerque, NM, and Livermore, CA (United States)
Four tensile coupon designs of PH13-8Mo H950 steel were tested to failure using quasi-static rates to obtain data to calibrate the Xue-Wierzbicki failure model for ductile fracture. The tests recorded the force-displacement, location of the first crack, displacement to fracture, area reduction, and crack propagation path. The test method and coupon designs were adopted from Tomasz Wierzbicki’s “Calibration and evaluation of seven fracture models” report. The XueWierzbicki model predicts fracture based on accumulated equivalent plastic strain, stress triaxiality, and deviatoric state parameter. Calibrating the Xue-Wierzbicki failure model required testing four coupon designs to calculate the four free parameters in the model. The coupon designs tested a range of stress triaxialities with two axisymmetric tests, one shear test, and one plane stress test. The data obtained and presented in this report can be used to develop a Xue-Wierzbicki fracture model for PH13-8Mo H950 steel.
