  • Resistance to Plane Stress Fracture (R Curve Behavior) of

    The R curve behavior of A572 Grade 50 steel was established over the temperature range 40 to +72°F by using state of the art procedures. Both linear elastic fracture mechanics (LEFM) and crack opening stretch (COS) analytical techniques were used in assessing experimental results obtained under load control and displacement control testing conditions.

  • A probabilistic approach for assessing discontinuities in

    Fig. 4 shows the difference in the probability of crack initiation between an edge crack (Fig. 2b crack type 3) and a through thickness crack (Fig. 2b crack type 1) for ASTM A572 Gr. 50 steel plates. An edge crack is more likely to initiate than a through thickness crack for the same stress level because a through thickness crack is confined by
