Download or read book Determination of Fracture Toughness by CTOD Resistance Curve Method written by SK. Putatunda and published by . This book was released on 1986 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture toughness ?i of AISI 4340 steel in the hardened and tempered condition has been determined by the multiple-specimen CTOD (crack tip opening displacement) resistance curve method. This fracture toughness ?i value has been compared with the JIc fracture toughness also obtained by the multiple-specimen JR curve technique. The investigation also examines the effect of specimen size, thickness, and width on ?i and ?R curve behavior. The effect of these parameters on the constraint factor m in the J-? relationship has also been examined. Compact tension specimens with TL orientation were used. All specimens satisfied ASTM E 813 standard size requirements.

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.

Download or read book Determination of Fracture Toughness of a Material That Exhibits Pop In Behavior written by SK. Putatunda and published by . This book was released on 1984 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture toughness of a material that undergoes pop-in crack extension was measured in two different heat treated conditions by a new procedure proposed in a recent publication. It is shown in this publication that the new procedure gives a size independent plane strain fracture toughness KIc value in thin and wide specimens prepared from relatively tough material. The present investigation examines the effect of width and the applicability of various approaches to fracture toughness measurement procedures, such as the new procedure, ASTM Test Method for Plane-Strain Fracture Toughness of Metallic Material (E 399), KIc, the ductile fracture toughness value JIc, and the crack growth resistance R curve, to a material that undergoes pop-in crack extension. The results show that whereas the new procedure can give a meaningful, reliable, and size independent fracture toughness even for a material that undergoes pop-in crack extension, the other methods, such as R curve, JIc, Kpop, or ASTM E 399 are inapplicable. The new procedure also shows that the K-KIc approach can be used in specimens whose thickness is 4.5 times less than that required by ASTM E 399.
