  • Dynamic ductile fracture propagation of pipeline steels was studied using 3D CZM.
  • JIS STPG370 steel was examined.
  • CZM calibrated for a small-scale specimen (DWTT) transferred to large-scale pipes.
  • Calibrated CZMs can be used to reproduce experimental data with good agreements.
  • The fracture velocities and the CTOAs are in good agreements.

  • 使用 3D CZM 研究了管线钢的动态韧性断裂扩展。
  • 检查了JIS STPG370钢。
  • CZM 针对转移到大型管道的小规模试样 (DWTT) 进行校准。
  • 校准的 CZM 可用于重现具有良好一致性的实验数据。
  • 断裂速度和 CTOA 吻合良好。
