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.

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).

Available in PDF, EPUB and Kindle. Book excerpt: Six-foot-wide plain plate specimens tested at an average applied stress of about 20 ksi, a temperature of 0 F, and with the notch-wedgeimpact method of initiation, produced fracture speeds in the range of 2000 to 4000 fps. Sixfoot-wide prestressed steel plates with a region of high tensile residual strain at each edge, and a region of residual compression in the central portion, tested at zero or 3 ksi average applied stress, at 0 F, and with impact initiation, produced fracture speeds of 6000 fps in the tensile zone near the initiation source, and speeds as low as 50 fps. Two-foot-wide centrally notched and welded specimens fabricated in different ways and tested at an average applied stress of about 10 ksi and a temperature of -40 F, produced speed within 1 1/2 inches of the initiation source and in a region of high residual tensile stress as high as 5000 fps; whereas speeds throughout the remainder of the specimen, which initially possessed a low compressive residual stress, were on the order of 1800 fps.

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.
