Download or read book Mixed mode I III Fracture Toughness of a Ferritic martensitic Stainless Steel written by and published by . This book was released on 1993 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The critical J-integrals of mode I (J{sub IC}), mixed-mode I/III (J{sub MC}), and mode III (J{sub IIIC}) were examined for a ferritic stainless steel (F-82H) at ambient temperature. A determination of J{sub MC} was made using modified compact-tension specimens. Different ratios of tension/shear stress were achieved by varying the principal axis of the crack plane between 0 and 55 degrees from the load line. Results showed that J{sub MC} and tearing modulus (T{sub M}) values varied with the crack angles and were lower than their mode I and mode III counterparts. Both the minimum J{sub MC} and T{sub M} values occurred at a crack angle between 40 and 50 degrees, where the load ratio of [sigma]{sub i}/[sigma]{sub iii} was 1.2 to 0.84. The J{sub min} was 240 Kj/M2, and ratios of J{sub IC}/J{sub min} and J{sub IIIC}/J{sub min} were 2.1 and 1.9, respectively. The morphology of fracture surfaces was consistent with the change of J{sub MC} and T{sub M} values. While the upper shelf-fracture toughness of F-82H depends on loading mode, the J{sub min} remains very high. Other important considerations include the effect of mixed-mode loading on the DBT temperature, and effects of hydrogen and irradiation on J{sub min}.

Book excerpt: The critical J integrals of mode I (J[sub IC]), mixed-mode I/III (J[sub MC]), and mode III (J[sub IIIC]) were examined for a ferritic stainless steel (F-82H) at ambient temperature. A determination of J[sub MC] was made using modified compact-tension specimens. Different ratios of tension/shear stress were achieved by varying the principal axis of the crack plane between 0 and 55 degrees from the load line. The results showed that J[sub MC]s and tearing moduli (T[sub M]) varied with the crack angles and were lower than their mode I and mode III counterparts. Both the minimum J[sub MC] and T[sub M] occurred at a crack angle between 40 and 50 degrees, where [sigma][sub i]/[sigma][sub iii] was 1.2 to 0.84. The J[sub min] was 240 kJ/m[sup 2], and ratios of J[sub IC]/J[sub min] and J[sub IIIC]/J[sub min] were about 2.1 and 1.9, respectively. Morphology of fracture surfaces was consistent with the change of J[sub MC] and T[sub M] values.

This book was released on 2012-12-06 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 1963 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using precracked Charpy tests supplemented by center-notched tensile tests, the fracture toughness of five low-alloy and three stainless steel high-strength alloys in sheet form was measured primarily as a function of heat treatment variables such as austenitizing and tempering temperatures. The low alloy steels studied were D6AC (two heats)4340 (martensitic and bainitic conditions), X200 (0.35 and 0.40% carbon), 300M and H11; and the stainless steels were AM 355, PH 15-7Mo and 301. For 4340, in the bainitic condition, the influence of subsequent deformation and aging on fracture toughness was also determined. In addition, preliminary studies of the effect of welding both before and after heat treatment on the toughness of H11, 300M and 4340 were carried out. (Author).
Download or read book Effect of Specimen Size on the Fracture Toughness of Type 304 Stainless Steel Interim Report written by and published by . This book was released on 1982 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of specimen size on the elastic-plastic fracture toughness behavior of Type 304 stainless steel was characterized by the multiple-specimen J-R curve technique at 427/sup 0/C. Fracture tests were performed on five compact specimen sizes: 2.5T (thickness = 63.5 mm), 2.5T (thickness = 14.7 mm), 1T (thickness = 25.4 mm), 1T (thickness = 14.7 mm), and 0.577 (thickness = 14.7 mm). In comparison with the 63.5-mm thick 2.5T specimen results, the smaller specimens exhibited higher J/sub Ic values and lower R-curve slopes (dJ/da). However, the differences in J/sub Ic/ and dJ/da were not statistically significant for the 2.5T and 1T specimens, which suggests that size effects for 1T and larger specimens are relatively small or nonexistant. On the other hand, there was a statistical difference between the 0.577T and 2.5T J/sub Ic/ values.
Download or read book Fracture Toughness and Impact Tests on Neutron Irradiated Ferritic Steels written by S. Chatterjee and published by . This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four A533B pressure vessel steels containing 0.16 wt% copper, nickel and phosphorous ranging from 0.10 to 0.82 wt% and 0.006 to 0.02 wt% respectively, and a AISI 403 stainless steel, a typical end fitting material used in pressurised heavy water reactors, in the unirradiated condition, were evaluated by instrumented impact testing to determine the crack initiation energy (CVNi), total absorbed energy (CVN), ductilebrittle transition temperature (T41J,T0.89mm), dynamic yield strength (?yd) and dynamic initiation fracture toughness (Kid). Three of these steels were irradiated at 563K to a nominal fast fluence of 1x1019, n/cm2 (E > 1 MeV) and the corresponding parameters were evaluated.
Download or read book A Closer Look at Effects of the Loading Rate on Fracture Toughness in the Ductile to Brittle Transition Regime of a Ferritic Steel written by Hans-Jakob Schindler and published by . This book was released on 2015 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: An increased loading rate causes not only a shift of the ductile-to-brittle transition curve, but also a slight change of the shape of this curve. The latter tends to become steeper as the loading rate increases. This effect was observed even at loading rates that are considered to be quasi-static according to ASTM E1921-13: Standard Test Method for Determination of Reference Temperature, T0, for Ferritic Steels in the Transition Range, Annual Book of ASTM Standards, ASTM International, West Conshohocken, PA, 2013. Actually, the coefficient 0.019 in the exponent of the MC turned out to be substantially higher at elevated loading rates. This means that a basic assumption of the evaluation procedure of ASTM E1921 is not met, which leads to an increased uncertainty of T0 or T0,x, respectively. This effect of is most pronounced in testing at elevated loading rates using the single-temperature option. An improved method to determine the reference temperature is proposed, where the exponent in the median transition curve in ASTM E1921 is considered to be an open parameter. The resulting reference temperatures, denoted as T100 andT100,x, respectively, are expected to be more accurate than standard T0, which is confirmed by comparison with experimental data. Furthermore, the validity requirements for T100 are less restrictive and more suitable than those in ASTM E1921, since they do not depend on the outcome of the tests. Based on the improved data, an improved estimation formula for the rate-induced shift of T0 is derived. Suggestions are made for improvement of ASTM E1921.

Download or read book Strain Hardening Effects on Fracture Toughness and Ductile Crack Growth in Austenitic Stainless Steels written by P. Balladon and published by . This book was released on 1985 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of cyclic and monotonic strain hardening on fracture toughness and ductile crack growth properties of 316 L stainless steel is determined using JIc and J-R curves. Cyclic strain hardening is performed by cyclic loading at different levels during precracking of specimens used for J-R tests. Monotonic strain hardening is done by controlled hot rolling of plate steel. The results obtained show that the fracture toughness is decreased by both cyclic and monotonic strain hardening. This decrease mainly affects crack initiation resistance (JIc) in the case of cyclic loading and only slightly influences crack growth resistance (dJ/da). For monotonic strain hardening, both JIc and dJ/da are strongly reduced at room and elevated temperatures. An attempt is made to determine the main factors responsible for these effects.
