This book was released on 1998 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture toughness testing of irradiated or aged materials is often limited due to the lack of available material. Subsize Charpy, small CT specimens or small punch test is generally used to overcome this limitation. In this paper, a method based on small notched tensile specimen testing is presented and used for evaluation of fracture toughness properties of a C-Mn steel with a large inclusions content. Specimens are cut in the radial and circumferential directions from a C-Mn steel pipe and tested at 100°C. The diameter of the smallest specimens is 3.6 mm. The average strain at fracture and finite elements simulation of the notched specimens are used to determine the critical values of a local ductile fracture criterion. These values are subsequently used in conjunction with finite element simulations to predict the fracture toughness of the material in different orientations. The predictions are compared with fracture toughness measured on 1⁄2 T, 1 T and 2 T-CT specimens.

Available in PDF, EPUB and Kindle. Book excerpt: As part of an increasing interest in radiation embrittlement for aging nuclear reactors, scientists gathered in New Orleans in January 1997 to consider the interests and capabilities of the scientific-testing community and of the commercial light-water-cooled power-reactor industry in terms of improving methods to characterize component integrity. The resulting 37 papers concentrate on the use of unique small and miniature specimens; nondestructive, nonintrusive, and in- situ test techniques for measuring mechanical and fracture properties; the application of tests to irradiation-induced embrittlement; and actual examples of tests to determine material integrity and to evaluate potential component life extension. They consider experimental, analytical, and computational aspects. Annotation copyrighted by Book News, Inc., Portland, OR

Book excerpt: A comprehensive survey is presented of current methods of fracture toughness testing that are based on linear elastic fracture mechanics. General principles are discussed in relation to the basic two-dimensional crack stress field model and in relation to real three-dimensional specimens. The designs and necessary dimensions of specimens for mixed mode and opening mode (plane strain) crack toughness measurement are considered in detail. Methods of test instrumentation and procedure are described. Expressions for the calculation of crack toughness values are given for the common types of specimens.

This book was released on 1969 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The yield strength range for steels from 180 to 210 ksi is currently covered by four weldable alloys of the following nominal chemical analysis: 18%Ni-8%Co-3%Mo maraging steel, 12%Ni-5%Cr-3%Mo maraging steel, 9%Ni-4%Co-0.20%C quenched and tempered (Q and T) steel, and 10%Ni-8%Co-2%Cr-1%Mo-0.10%C Q and T steel. Broad ranges of fracture resistance have been reported for these materials based on various fracture tests, and this report presents information for material selection and design guidance by providing an analysis of the interactions between the metallurgical and mechanical parameters that contribute to the fracture resistance of plate products. Definitions of the interaction between the metallurgical and the mechanical aspects are developed with the use of the Dynamic Tear (DT) test and the Ratio Analysis Diagram (RAD). (Author).

Download or read book Use of Thickness Reduction to Estimate Fracture Toughness written by R. deWit and published by . This book was released on 1993 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: To help predict the behavior of a nuclear pressure vessel undergoing pressurized thermal shock, values of the arrest toughness are required. The purpose of the work described here is to show how toughness values can be calculated from the thickness reduction (TR) of the tested specimens and then used as "lower-bound" estimates. In the NIST wide-plate crack-arrest test program, 16 single edge-notched tension specimens were fractured, using the 26.7 MN universal testing machine. The first series of tests used HSST A533 Grade B Class 1 quenched and tempered steel, while the second series used a low upper-shelf 21/4 Cr-1 Mo steel. For each specimen the TR was measured on the two halves of the broken specimen and a contour map was constructed. The thickness reduction, TR, along the crack propagation plane can be related to the toughness, K, by the relationship K2 = E • ?Y • TR, where E is Young's modulus and ?Y an estimate of the tension effective yield strength adjusted for temperature, strain-rate, and constraint. The results show good agreement with values of K for arrest and reinitiation computed from a finite-element generation-mode analysis. Therefore, the indication of plastic work rate provided by the thickness reduction near the fracture plane is a useful preliminary assessment of the fracture toughness.
