Integration of Analytical Procedures for Fracture-Safe Design of Metal Structures

摘要

An interpretive review is presented of the development of scientific knowledge of fracture processes and of the technological application of this information to the evolution of rational engineering principles for fracture-safe design. Discussions of mechanical, metallurgical, and structural aspects of the subject emphasize that engineering design practices must involve detailed consideration of all factors. The evolution of modern fracture-safe design practices began in 1950. The results of the earlier research provided a base from which definitive studies were evolved. The development of significant fracture-characterization test methods and of procedures for their analytical interpretation paced the rate of progress during this time period. A description is provided of fracture tests which are suitable for evolving data-bank references of metal properties, required for general engineering practice of fracture-safe design. Major emphasis is placed on procedures based on the use of analysis diagrams, which provide for cross-referencing between structural factors and metal properties. The primary aim of the text is to present the case for the utilization of modern practices in the design of engineering structures. (Author)
