Download or read book Fatigue of Ren 41 Under Constant and Random amplitude Loading at Room and Elevated Temperatures written by Edward P. Phillips and published by . This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Narrow-band random-amplitude and constant-amplitude bending fatigue tests were conducted on sharply notched Rene' 41 specimens at room temperature, 700 degrees F (644 degrees K), and 1400 degrees F (1033 degrees K). When compared on the basis of the root mean square of the nominal peak stresses, the random loading generally gave shorter lives than the constant-amplitude loading. Theoretical life predictions were made for the random-loading tests by using the Palmgren-Miner cumulative-damage rule and two different peak stress distributions (the distribution determined from the tests and the classical Rayleigh distribution). The predictions under-estimated the fatigue life in practically all cases. The predicted lives based on the Rayleigh peak distribution were always less than those predicted by using the experimentally determined peak distribution. For both types of loading in the long-life region, a loss of fatigue strength from that at room temperature occurred at 700 degrees F (644 degrees K) but no further loss occurred at 1400 degrees F (1033 degrees K).

Download or read book Cumulative Fatigue Damage at Elevated Temperature written by William K. Rey and published by . This book was released on 1958 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study of cumulative fatigue damage at elevated temperatures was conducted using heat-treated SAE 4130 alloy steel. The S-N curves at room temperature, 400 degrees F, and 800 degrees F were obtained from rotating-beam fatigue tests. Two-step, three-step, and five-step cumulative-damage fatigue tests were conducted on rotating-beam fatigue specimens at room temperature, 400 degrees F, and 800 degrees F. The results of the cumulative damage tests are compared with those of a theoretical analysis.

Book excerpt: The advanced liquid-propellant rockets for the exploration of space use liquefied gases as part of the fuel mixture. The Atlas and Titan ICBM's and the Saturn booster employ liquid oxygen as an oxidizing agent, and liquid- hydrogen rocket engines are being developed for the upper stages in the Saturn booster system. Oxygen and hydrogen are an efficient combination of oxidizer and fuel, if they can be employed in the liquid state. In order to maintain these reactants as liquids, they must be stored at or below their boiling temperatures (-297 F for oxygen and 423 F for hydrogen at normal atmospheric pressure). There are many problems, associated with the storage and handling of these cryogenic fluids, which must be considered in the design and fabrication of tankage and other components of such systems. Thus, a continuing program is being conducted by the Propulsion and Vehicle Engineering Laboratory of the Marshall Space Flight Center to evaluate the applicability of various metallic materials at cryogenic temperatures. The severest limitation on the use of certain metals at low temperatures is that imposed by the increasing susceptibility to brittle failure as the temperature decreases Just as with materials used for any other structural purposes, strength, ductility, and toughness are important considerations in most cryogenic applications. The studies at the Marshall Space Flight Center have emphasized these aspects of materials behavior in evaluating the mechanical properties of the materials discussed in this review.
