Available in PDF, EPUB and Kindle. Book excerpt: This important, self-contained reference deals with structural life assessment (SLA) and structural health monitoring (SHM) in a combined form. SLA periodically evaluates the state and condition of a structural system and provides recommendations for possible maintenance actions or the end of structural service life. It is a diversified field and relies on the theories of fracture mechanics, fatigue damage process, and reliability theory. For common structures, their life assessment is not only governed by the theory of fracture mechanics and fatigue damage process, but by other factors such as corrosion, grounding, and sudden collision. On the other hand, SHM deals with the detection, prediction, and location of crack development online. Both SLA and SHM are combined in a unified and coherent treatment.

This book was released on 1988 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of six wide-plate crack-arrest tests was recently completed by the Heavy-Section Steel Technology program at the National Bureau of Standards, Gaithersburg, MD, using tensile-loaded specimens of A533 Grade B Class 1 steel. Crack-arrest data were obtained at temperatures in the transition range and above the onset of the Charpy upper shelf, thereby providing a basis for the development and evaluation of improved fracture-analysis methods. The 1 by 1 by 0.102-m single-edge-notched (SEN) specimens were welded to long straight pull tabs and subjected to a transverse linear temperature gradient before loading. The crack tips were sharpened by hydrogen-charging an electron-beam weld. The tests were designed to obtain crack arrest near the middle of the specimen where the temperature would produce a high-toughness level in the upper transition region of the material. The specimens were instrumented with strain gages and thermocouples. Initial static design calculations were made using textbook formulas. Additional calculations, using an assumed set of KID versus ?a and T relations and an effective stress wave concept, confirmed the reasonableness of tentative design parameters. Pretest and posttest dynamic finite-element calculations were performed for each test. Computed results are compared with transient data for crack-line strains, crack speed, crack-opening displacement, arrest location, and postarrest tearing. Results from both application-mode and generation-mode dynamic analyses are presented. The arrest toughness values calculated from the test data are summarized for temperatures ranging from the transition into the Charpy upper-shelf range.

Available in PDF, EPUB and Kindle. Book excerpt: A greatly scaled-down version of the wide plate crack arrest test has been developed to characterize the crack arrest performance of a high strength, low alloy (HSLA) steel alloy in the upper region of the ductile-brittle transition. The specimen is a single-edge notched, 152 mm wide by 19 mm thick by 910 mm long plate subjected to a strong thermal gradient and a tensile loading. The thermal gradient is required to arrest the crack at temperatures high in the transition region, close to the expected service temperature for crack arrest applications in surface ships. Strain gages are placed along the crack path to obtain crack position and crack velocity data, and this data, along with the applied loading is combined in a "generation mode" analysis using finite element analysis to obtain a dynamic analysis of the crack arrest event. A prior investigation demonstrated the feasibility of the technique and this investigation was devised to obtain a larger dataset of crack arrest toughness values of an HSLA-100 steel plate to better characterize the upper transition crack arrest performance of this alloy. Brittle crack initiation, significant cleavage crack propagation, and subsequent crack arrest was achieved in all eight of the tests conducted in this investigation. The cleavage cracks were observed to propagate at nearly constant velocity, typically in the range of 350-400 m/s before arresting abruptly. A crack arrest master curve approach was used to characterize the fracture toughness and a crack arrest reference temperature, TKIA = -136°C was determined for the HSLA-100 plate. This corresponded to a shift in the crack initiation reference temperature of +36°C. The shift in reference temperature was much less than that observed for low Ni steel alloys.
