This book was released on 2013-12 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: As part of an effort to apply damage tolerance concepts to railroad tank cars, the fatigue crack growth (FCG) behavior of two lots of TC-128B steel was investigated. In addition to the material lot difference, variables assessed include: load ratio, orientation, environment, and crack growth test technique. The two material lots yielded essentially identical FCG properties for low and high stress ratios. The influence of stress ratio was slight, except in the near-threshold regime.

Book Synopsis Variable Amplitude Fatigue Crack Growth Characteristics of Railroad Tank Car Steel by : U.s. Department of Transportation
Download or read book Variable Amplitude Fatigue Crack Growth Characteristics of Railroad Tank Car Steel written by U.s. Department of Transportation and published by CreateSpace. This book was released on 2013-12 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The load history that railroad tank cars experience has a significant variable amplitude characteristic. Although previous efforts have been directed toward understanding baseline fatigue crack growth behavior of TC-128B steel as a function of material lot, orientation, and environment, little is known regarding how load interaction impacts crack growth behavior in a typical tank car steel. Load interaction occurs when the variable amplitude character of the loading results in crack growth that differs as a function of load history effects in the wake of the crack. The focus of this testing effort was to determine empirically how TC- 128B behaves under these types of simplified loading conditions. The data provided in this report links the constant amplitudeloading regime to the more complex variable amplitude-loading regime that tank cars experience during in-service use. The data can also be used as modeling guidelines to better understand the role of variable amplitude loading on TC-128B.

Book Synopsis On the Use of Numerical Models to Design Fatigue Crack Growth Tests for a Railroad Tank'Car Spectrum by : WT. Riddell
Download or read book On the Use of Numerical Models to Design Fatigue Crack Growth Tests for a Railroad Tank'Car Spectrum written by WT. Riddell and published by . This book was released on 2002 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The railroad tank car industry is moving toward damage-tolerance-based inspection intervals to maintain the safe and efficient transport of hazardous materials by rail. One aspect of this effort is predicting fatigue crack growth rates that result from railroad tank car service conditions. A fracture mechanics parameter, H, is proposed to relate the crack-tip driving force under a railroad tank car spectrum to the resulting crack growth rates. This approach will allow the direct application of fatigue crack growth rate data resulting from laboratory tests to models for crack growth under railroad service conditions. However, for this approach to be successful, it is essential that similitude between lab tests and the structural application is maintained, so that fatigue crack growth rates are predicted correctly. Two crack-closure-based models are used to predict the effects of various laboratory test design parameters on fatigue crack growth rates for the loaded vertical coupler force (LVCF) spectrum, which describes the vertical coupler forces for a loaded railroad tank car. Random ordered load blocks are predicted to result in growth rates approximately twice as great as those resulting from either low-high or high-low ordered blocks. Truncating even the smallest amplitudes from the spectrum was predicted to affect crack growth rates. The most significant effect predicted was that of the far-field stress level. Although changes in stress level are predicted to have only a minor affect (approximately 20%) on constant-amplitude fatigue crack growth rates, corresponding changes in stress level are predicted to affect variable-amplitude fatigue crack growth rates by up to a factor of six. These results suggest that tests designed to determine fatigue crack growth rates for the LVCF spectrum must be considered carefully, and that crack closure based models for fatigue crack growth are a valuable tool for designing such tests.
Book Synopsis A Methodology for Assessing Fatigue Crack Growth Reliability of Railroad Tank Cars by : W. Zhao
Download or read book A Methodology for Assessing Fatigue Crack Growth Reliability of Railroad Tank Cars written by W. Zhao and published by . This book was released on 2004 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A methodology for assessing structural reliability of railroad tank cars undergoing fatigue crack growth is being developed. A three-degree-of freedom (3-dof) surface crack is employed to account for an asymmetric stress field existing at a fatigue critical location in tank car structures. A fatigue life prediction program using the Walker equation to account for stress ratio effects is developed for the 3-dof surface crack model. A component reliability problem is formulated as a limit state function and solved using a first-order reliability method along with importance sampling method within the commercial reliability software, STRUREL. The methodology is demonstrated using illustrative railroad tank car examples. The results show that: (a) failure probability, Pf, increases as tank car mileage increases; (b) welding residual stresses in the tank structure can significantly increase Pf ; (c) uncertainty in the stress amplitude also has a significant effect on Pf; and (d) the correlation between initial crack depth and initial crack aspect ratio is an important parameter.
Book Synopsis Fatigue Crack Growth and Fracture Behavior of Bainitic Rail Steels by : Heshmat A. Aglan
Download or read book Fatigue Crack Growth and Fracture Behavior of Bainitic Rail Steels written by Heshmat A. Aglan and published by . This book was released on 2011 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microstructure-mechanical properties relationships, fracture toughness, fatigue crack growth and fracture surface morphology of J6 bainitic, manganese, and pearlitic rail steels were studied. Microstructure-mechanical properties correlation of the three rail steels under consideration revealed that the bainitic rail steel has the highest mechanical properties as compared with austenitic manganese steel (AMS) and pearlitic rail steels. AMS shows very few signs of being work hardened or toughened, which usually increases the mechanical properties of the material. In pearlite, the microstructure has more detailed features that contribute to its mechanical properties. The bainitic steel has more alloying elements that when mixed, create so many dislocations that the dislocations cannot move against each other. This is where bainitic steel derives its strength. Fracture toughness analysis (KIc) of the three rail steels, namely bainitic, manganese and pearlitic was performed. A valid KIc was determined for the pearlitic and bainitic steels based on the American Society of Testing and Materials (ASTM) E399 criteria.

Download or read book Fatigue Crack Propagation in Rail Steels written by D. Broek and published by . This book was released on 1978 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baseline fatigue crack growth data at R = 0 and mechanical property data have been generated on 66 different rail materials which are in service on U.S. railroads. These data are evaluated, along with metallurgical variables such as chemical composition and microstructure, in an attempt to develop a correlation of mechanical and metallurgical factors affecting crack behavior in rail steels. The ultimate objective of this effort is the development of a rail failure model to enable the determination of safe inspection intervals, through prediction of fatigue crack growth in rail under service loading.
Book Synopsis Fatigue Crack Growth Behavior of a High-Strength Steel by : Maurice F. Amateau
Download or read book Fatigue Crack Growth Behavior of a High-Strength Steel written by Maurice F. Amateau and published by . This book was released on 1971 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth behavior of high-strength Ladish D6AC steel was examined under various conditions of frequency, environment, temperature, stress ratio, and stress intensity history. Materials with fracture toughness ranging from 50 to 100 ksi/sq. in., but with the same yield strength of 220 ksi, were examined. Variations in fracture thoughness do not have a strong effect on crack growth rate at stress intensity levels within the log-linear portion of the crack growth curves. Different environments, such as dry air, laboratory air, and distilled water, were found to produce different fatigue crack growth behavior at 1 Hz but not at 10 Hz loading frequency. The lowest crack growth rate occurred in dry air, while the aggressive environment of distilled water affected the crack growth rate more severly at lower stress intensity levels. The effects of temperature over the range from -40 to 175F are a uniform shift of the growth curve to low crack growth rates and a lowering of the stress intensity level for the onset of rapid fatigue crack propagation. Suppression of crack growth rate following high prior stress cycles is the most significant effect of stress history. This effect cannot be explained in terms of the relative plastic zone sizes alone. (Author).

It has been remarked that the discovery of many of our medicinal springs has been due to some romantic incident, or, in other cases, to some occurrence partaking almost of the ludicrous. At the famed Carlsbad, for instance, a princely hunter pursues his stag into the lake where it has sought refuge, whereupon the unusual cries of his hounds, too eagerly breasting the waters, speedily reveal to him the strongly thermal nature of the spring which feeds the lake, and the discovery has benefited the thousands who annually frequent that health-giving resort from almost every land. On the other hand, in the case of our own Bath, although well known to the ancient [...]".
