Download or read book Chevron Notched Specimens for Fracture Toughness Measurements Independent of R Curve Effects written by LM. Barker and published by . This book was released on 1989 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: A relatively new plane-strain fracture toughness test method based on chevron-notched test specimens has created a keen interest in comparing toughness measurements by the new method against measurements by the conventional method (ASTM E 399). Tests of various aluminum alloys by the two methods have shown a divergence in test results at the higher toughness levels. The rising R-curve effect in tough aluminums has been cited as one of the factors contributing to the observed discrepancy. This paper shows why the chevron-notched test results are independent of rising R-curve effects, whereas ASTM E 399 tests often are not. The E 399 test dependence on the rising R-curve constitutes a specimen size effect, and this dependence is partly responsible for the divergence between chevron-notched and E 399 tests of tougher aluminums. The chevron-notched method produces the toughness values which would be obtained from E 399 measurements if sufficiently large E 399 specimens could be tested.

Download or read book ASTM E 1304 The New Standard Test for Plane Strain Chevron Notched Fracture Toughness written by LM. Barker and published by . This book was released on 1992 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The origins and rationale for the three plane-strain fracture toughnesses defined by the new ASTM Test Method for Plane-Strain (Chevron-Notch) Fracture Toughness of Metallic Materials (E 1304-89) are reviewed. KIvM represents the toughness measured in a greatly simplified test, but it can be less accurate than KIv and KIvj. The test for KIv is complete with all the procedures and validity criteria necessary to assure accurate measurements of plane-strain critical stress-intensity factors. When a material exhibits a crack-jump behavior, the KIv procedure must be modified, and the toughness is called KIvj. This paper suggests that ASTM E 1304-89 toughness measurements can be used for the full range of applications appropriate to KIc values measured by the ASTM Test Method for Plane-Strain Fracture Toughness of Metallic Materials (E 399-83). However, a material-dependent constant, equal to about three times the ctack-tip plastic zone radius, should be added to the preexisting flaw size in calculations of crack stability.

Download or read book Chevron Notch Bend Testing in Glass written by L. Chuck and published by . This book was released on 1984 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study describes experimental difficulties in the use of the chevron-notch bend test to determine the plane-strain fracture toughness, KIc, for brittle materials. Four-point flexure tests were performed on soda-lime-silica glass and vitreous silica in both "wet" and "dry" environments and at various loading rates. Results show that an inability to produce stable crack growth in the chevron-notch bend test can lead to serious overestimates of KIc as well as to significant scatter in the data. It is also shown that water enhanced crack growth can reduce the measured value of KIc.

This book was released on 1992 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture toughness tests were conducted at room temperature and at - 196°C on a martensitic stainless steel that had been quenched and tempered to a hardness of Rockwell C 61-63. The fracture toughness specimens were chevron-notch, short-bar specimens for which B was 12.7 mm and W was 25.4 mm. Tests were conducted in accordance with ASTM Test Method for Plane-Strain (Chevron Notch) Fracture Toughness of Metallic Materials (E 1304-89).
