A NUMERICAL STUDY ON CRACK GROWTH RESISTANCE CURVE OF X70 STEELS Conference Paper uri icon

abstract

  • In this work a phenomenological approach is employed for fracture initation and propagation in SENT specimens. Modified Mohr-Coulomb (MMC) fracture criterion establish the initiation of damage/fracture at the critical material point and the post-initation softening controls its rate of propagation. By means of a tridimensional mixed stress state (equivalent plastic strain, p; Triaxiality, ; and Lode angle, ) the nature of the growing crack front can be explained.
