Available in PDF, EPUB and Kindle. Book excerpt: A fundamental fracture mechanics investigation was concerned with studies of the propagation of brittle fractures in wide steel plates in an attempt to delineate many of the parameters associated with a propagating fracture, and in particular to study the strain field surroundingA PROPAGATING BRITTLE FRACTURE. Tests were made on structural-steel plate specimens, either 2 or 6 ft in width. In most cases the plate specimens were stressed uniaxially to about 19,000 psi, cooled to about 0 F, and a fracture was started with the notch-wedge-impact method of fracture initiation. Measurements of the strain distribution on the surface of the plate and the crack spee were made as the fracture traversed the plate. The majority of the recorded fracture speeds ranged fr m 2000 to 4000 fps. the strain field surrounding the tip of an advancing fracture appeared to remain essentially unchanged after traversing about one-third the width of a 6-ft-wide plate. Exploratory studies were also made of the propagation of brittle fractures in prestressed plates. Analytical studies of plate response incated that the lattice representation is a promising method of studying plate response during fracture propagation. (Author).

This book was released on 1961 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five plates were prepared and tested; the residual strain field was produced by welding tapered slots cut in the edges of the specimen. The test results clearly showed that the high residual tensile strain at the initiation edge aided the fracture initiation. For specimens with no external applied load, the fractures arrested before completely crossing the specimens; for specimens with external applied loads, even though low in magnitude, the fractures propagated completely across the plates. The recorded fracture speeds were much lower than any previously noted in tests of six-foot-wide plates, ranging from about 4000 fps near the initiation edge to as low as 50 fps in the compressive strain region. The strain response as measured by gages located at various points across the plate showed that the magnitude of peak strain and the size of the strain field associated with the moving crack tip diminished as the fracture propagated through the compressive strain field at reduced speeds.

Book excerpt: This investigation was undertaken to study lowvelocity brittle fracture in wide steel plates. The detailed results of two tests of 6-ft-wide prestressed steel plates are presented along with pertinent observations from tests of similar specimens; also, results of nineteen tests of 2-ft-wide centrally notched plates. In 6-ft-wide prestressed plates, the residual stress field (longitudinal tensile stresses at the edges of the plate balanced by compressive stresses throughout the central portion) made initiation possible with no external applied stress, and had a significant effect on the fracture propagation. Fracture speeds were high (4000-6000 fps) near the edges of the plates and decreased rapidly to as low as l65 fps as the fracture propagated into the region of compressive stresses. In the lowspeed regions the magnitude and extent of the dynamic strain field associated with the crack tip was considerably less than had been recorded in earlier tests of high-speed fractures in plain plates.

Available in PDF, EPUB and Kindle. Book excerpt: Brittle Fracture in Steel Structures emphasizes the prevention of brittle fracture in structures fabricated from mild and low alloy steel operating at normal ambient temperatures. This book is divided into seven chapters. Chapter 1 provides the historical background and summarizes numerous case histories of brittle fractures. The nature of the phenomenon and factors that influence brittle fracture, including various methods of testing to determine the notch ductilities of different steels are described in Chapters 2 to 4. The fifth chapter elaborates the design considerations affecting the choice of steel for structural applications. Chapter 6 reviews the main methods for assessing the degree of notch ductility needed for different applications, while Chapter 7 deliberates practical procedures, recommended by the Navy Department Advisory Committee on Structural Steels, for assessing the suitability of different steels for particular applications. This publication is beneficial to metallurgists and welders intending to acquire knowledge of mild steel structures fabricated by welding from rolled steel plates and sections.
