This book was released on 1974 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: When an airframe component breaks suddenly, under conditions well within the design envelope, the occurrence is usually termed brittle fracture. This report uses an analytical scheme which combines data from several different sources in order to provide diagrams of fracture resistance versus thickness for a number of 'standard' yield strength levels. By using such diagrams, limited data on a new alloy or heat treatment may be compared, and the impact on designs where fracture resistance is important may be assessed. The data background employed in the analysis consisted of both iron- and aluminum-base airframe materials. However, this report focuses largely on the 7000-series aluminum alloys. Minimum expected behavior has been developed for this series of aluminum alloys by examining fracture toughness, yield strength, and thickness effect in accordance with the analytical scheme described.

Book Synopsis Static and Dynamic Fracture Properties for Aluminum Alloy 7475-T651 and by :
Download or read book Static and Dynamic Fracture Properties for Aluminum Alloy 7475-T651 and written by and published by . This book was released on 1975 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A broad base of mechanical property data were developed on two plates of Al 7475. One of the 1-1/2-inch thick plates was in the T7351 condition and one was in the T651 condition. The tensile properties of the T651 plate were higher than those of the T7351 plate. Nearly all of the fracture toughness tests were invalid by ASTM test standards; those that were valid indicate the material possesses good toughness. The conditional toughness values (K sub Q) for identical test conditions indicate the T7351 processing possesses the superior toughness property. The smooth and notched fatigue properties were about equal to those of other 7000-series aluminum alloys. Constant amplitude fatigue crack growth resistance was better than some older 7000-series alloys and similar to other new 7000-series alloys while the stress corrosion cracking properties in a salt water environment were excellent. Most of the tests were repeated using specimens that had been subjected to 250 F (121 C) for 1000 hours. This time- temperature exposure resulted in: (1) a slight reduction in tensile strength, (2) a slight increase in conditional toughness (K sub Q) for the T651 plate and a small decrease in K sub Q for the T7351 heat treated plate, (3) a slight reduction in fatigue properties, and (4) negligible effect on the fatigue crack growth rate and corrosion properties.
Book Synopsis Crack Resistance Properties of High Strength Aluminum Alloys by : Carl M. Carman
Download or read book Crack Resistance Properties of High Strength Aluminum Alloys written by Carl M. Carman and published by . This book was released on 1965 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fracture toughness of both commercial and high purity aluminum alloys of the 7000 and 2000 series was determined by means of the center notched sheet specimen. The instability conditions described here give reproducible and well defined values of fracture toughness. For the very high strength aluminum alloys, the four inch wide specimen is sufficiently large to give accurate values of fracture toughness. Both the compliance and photographic method give the same value of fracture toughness, provided the proper experimental conditions are met. The testing conditions for the 2000 series of aluminum alloys do not conform to the normal requirements for simple fracture mechanics analysis, but the data may be analyzed within the framework of a refined instability model. The fracture toughness of the 2000 series of aluminum alloys is greater than the fracture toughness of the 7000 series. Reduction of iron and silicon contents results in an upgrading of the fracture toughness for both 7075-T6 and 2024-T4 aluminum alloys. Quantitative fractography gives some insight into the mechanisms which may be responsible for the upgrading of the fracture toughness. (Author).

This book was released on 1969 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpretations of fracture toughness characteristics as measured by various test procedures are presented for structural aluminum alloys. Quantitative definitions of the significance of engineering fracture toughness tests are provided by extension of analytical procedures evolved from fracture mechanics theory. The procedural simplicity of the engineering tests coupled with the analytical capabilities of fracture mechanics theory provides for a significant advancement in fracture-safe design procedures for aluminum alloys covering the full range of yield strength.

Book excerpt: A Specialists Meeting was held by AGARD to deal with questions dealing with the microstructure and variations of microstructure of various aerospace alloys and the associated effects on fatigue and fracture resistance, the effects of variations in chemical composition, processing and heat treatment on microstructure, and the related possibilities of achieving higher fatigue and fracture resistance by changes in chemical composition, processing procedures and heat treatment, without serious penalties relative to static strength and corrosion resistance properties. This Conference Proceedings contains the text of six papers given at the meeting and a summary of the discussions. Aluminum, Titanium and Ferrous Alloys were covered.
Book Synopsis Fracture Extension Resistance of Aluminum Alloys in Thin Sections by : Ralph W. Judy
Download or read book Fracture Extension Resistance of Aluminum Alloys in Thin Sections written by Ralph W. Judy and published by . This book was released on 1973 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dynamic Tear (DT) test was developed to characterize the fracture resistance properties of structural metals over the entire range of strength and fracture properties. Ratio Analysis Diagram (RAD) procedures based on use of the DT test have been developed as a framework for determining the significance of fracture resistance data in terms of structural design papameters. However, DT test methods have been used primarily for thick-section materials (1.0 in. and thicker); hence no standard method for measuring fracture properties of thin-section ductile materials presently exists. This report is concerned with the extension of DT test methods to include thin-section materials in the RAD analysis system. The test materials were four thin-section aluminum alloys. A technique of laminating specimens was developed to prevent specimen buckling. Methods for comparing thin-section material properties to previously established data for aluminum alloys in thicker sections on the RAD format are also discussed. (Author).

Download or read book Fracture-Safe Design of Aluminum and Titanium Alloy Structures written by R. J. Goode and published by . This book was released on 1972 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fracture resistance characterization information obtained from the Dynamic Tear and K sub Ic test methods for high- and ultrahigh-strength aluminum and titanium alloys is summarized. These tests have been used to establish the fracture resistance characterizations for these materials covering a wide range of yield strength and metallurgical conditions. Ratio Analysis Diagram procedures have been evolved for translating this information into structural mechanics predictions for fracture. The general physical metallurgical characteristics for the generic families of these materials are discussed in relation to their potentials for optimizing aluminum and titanium alloys to high levels of fracture resistance.
