THE APPLICATION OF FRACTURE CONTROL PRINCIPLES TO FREIGHT CAR CENTER-SILL STRUCTURES

Impact tests using Dynamic Tear samples were conducted on ASTM A36, A441, and A572 steels to determine their resistance to brittle fracture. The effects of grain size were also studied by normalizing plates of the as-received steel. Modern fracture control principles are applied to the data to predict the service behavior of these steels.
