Abstract: Since World War II, periodic changes in the fabrication, design, and material specifications for ship steels have been made to preclude brittle fractures. These various changes are described ...

Abstract: To determine the crack-toughness behavior of steels subjected to high strain rates, a study was undertaken to establish the effects of strain rate and temperature on the KIc -values of steels. ...

Abstract: Previous studies have shown that there is an increase in cleavage fracture toughness of laboratory specimens with shallow flaws compared with those laboratory specimens having deep flaws. Typical ...

Abstract: Studies by the Subcommittee for Effective Utilization of Yield Strength of the Pressure Vessel Research Committee of the Welding Research Council have provided a better understanding of the ...

Abstract: Increasing use of high-strength steels in pressure-vessel design has resulted from emphasis on decreasing the weight of pressure vessels for certain applications. To demonstrate the suitability ...

Abstract: Constraint, as related to specimen crack depth (a ) or crack depth to specimen width ratio (a/W ), can have a significant effect on fracture toughness. In laboratory specimens, both crack ...

Abstract: During fabrication, the cold forming of structural components may reduce the yield strength of a component if it is loaded in a direction opposite to that of the cold forming. This reduction ...
