Question
A Charpy V Notch test was conducted for a steel specimen. The average val-
ues of the test results at four different test temperatures were found to be
15 J at -45°C
21 J at -18°C
60 J at 5°C
75 J at 40°C
A bridge will be located in a region where specifications require a minimum
of 35 J fracture toughness at 0°C for welded fracture-critical members. If the
bridge contains a welded flange in a fracture-critical member, does the steel
have adequate Charpy V notch fracture toughness to be used for this bridge?
