Ship Structure Committee Publishes Two Reports On Strength Of Materials

The Ship Structure Committee has recently published two new reports of interest to naval architects and engineers who are involved in the sciences of fracture mechanics and strength of materials. SSC-275, "The Effect of Strain Rate on the Toughness of Ship Steels," develops data for a variety of steels at various loading rates and temperatures to assist in determining the resistance of these steels to crack initiation and propagation.

SSC-276, "Fracture Behavior Characterization of Ship Steels and Weldments," is a companion report to SSC-275. This report provides additional experimental test data for ship steels and weldments from a series of large-scale tests typical in configuration and design to ship hull construction and a variety of service.

The Ship Structure Committee is an interagency committee composed of representatives from the Naval Sea Systems Command, Maritime Administration, U.S. Coast Guard, Military Sealift Command, U.S. Geological Survey, and the American Bureau of Shipping. The purpose of the Committee is to conduct an aggressive research program which will, in the light of changing technology in marine transportation, improve the design, materials and construction of the hull structure of ships and other marine structures. This is accomplished by an extension of knowledge in these fields for the ultimate purpose of increasing the safe and economic operation of all marine structures.
