Available in PDF, EPUB and Kindle. Book excerpt: The Memorandum discusses the current situation on the inclusion of fracture-toughness testing requirements in specifications for high-strength steels used for military applications. The Memorandum was prepared at the request of The Technical Cooperation Program (TTCP), and contains information from Canadian and British members of that program, as well as U.S. information. Military applications discussed include missile motor cases, aircraft landing gear, gun tubes, armor plate, and hydrofoils. (Author).
Download or read book Current Methods of Fracture toughness Testing of High strength Alloys with Emphasis on Plane Strain written by J. E. Campbell and published by . This book was released on 1964 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture-toughness testing using principles of fracture mechanics has developed to the point where it can be used as a basis for selection of materials, for estimating limiting design stresses assuming the presence of small flaws, and for analyzing failures. Current methods of measuring plane-stress and plane-strain fracturetoughness parameters are presented in this report. The specimens include center-cracked, edge-cracked, single-edge-cracked, surface-cracked, and notched round bars, which are subjected to tensile loading, and notched bars for bend tests. The different types of specimens permit evaluating sheet, plate, bar stock, and forgings as well as material from failed structures. Application of fracture-toughness parameters to design of high-strength structures is reviewed for both static and fatigue loading. Consideration of the fracture-mechanics concepts in design should lead to fewer problems with brittle fracture in high-strength structures. (Author).

Download or read book Crack Arrest Fracture Toughness of Armor Steels written by E. J. Ripling and published by . This book was released on 1987 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for evaluating break up, or shattering anc cracking may be by the use of the crack arrest fracture toughness, Ka. Use of this Ka would not be restricted to steels, but could be applied to other armor materials also. The crack arrest fracture toughness, KIa, of the two steels were shown to be different, the 4130 being tougher than 4340. The significance of this can only be ascertained by comparing these results with ballistic test data. Keywords: High strength steels; Armor plate; Transition temperatures; Fracture toughness; Mechanical properties; Dynamic properties; Crack propagations; Ballistic testing.

Download or read book The Effect of Loading Rate and Temperature on the Fracture Toughness of High Strength Steels written by David P. Kendall and published by . This book was released on 1970 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of loading rates, ranging from 10 to 100,000 ksi square root of (in/sec), and temperatures, ranging from room temperature to -100F, on the plane strain fracture toughness of several high strength alloy steels has been determined. Materials investigated are a commercial 4340 steel, a modified 4330 steel from a gun tube forging having three different heat treatments and two different heats of 250 grade maraging steel. Test specimens utilized are essentially ASTM 'compact tension' type specimens of one inch thickness. Tests were conducted on an open loop, hydraulic, high loading rate tensile testing machine. Results are presented in the form of graphs of fracture toughness versus temperature for the maximum and minimum loading rates ('dynamic' and 'static'). Fracture toughness versus loading rate at -60F and yield strength versus elastic strain rate at room temperature, -60F and -100F for one heat of maraging steel are also reported. (Author).
