Book Description
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).

Current Methods of Fracture-toughness Testing of High-strength Alloys with Emphasis on Plane Strain
Author: J. E. Campbell
Publisher:
ISBN:
Category : Alloys
Languages : en
Pages : 32
Book Description
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).

Crack Arrest Fracture Toughness of Armor Steels
Author: E. J. Ripling
Publisher:
ISBN:
Category : Fracture mechanics
Languages : en
Pages : 72
Book Description
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.
