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.

This book was released on 1993 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cumulative fatigue damage behavior of the cast nickel-base superalloy, MAR-M 247 (in a fine grain form), was characterized experimentally at room temperature in ambient air and in high-pressure gaseous hydrogen. The material was first characterized in simple fatigue, consisting of fully reversed strain- and load-controlled axial fatigue tests. These data were used to establish the reference life behavior for use in the cumulative fatigue experiments. The principal tool used to study the cumulative damage behavior was the two-level loading test (single-block) wherein low-cycle fatigue loading is applied initially to the specimen for various low-cycle fatigue life fractions, and the specimen is subsequently cycled under high-cycle fatigue conditions to failure. MAR-M 247 was found to exhibit a strongly nonlinear cumulative interaction behavior, with the remaining high-cycle fatigue life capability in the second load level reduced by as much as a factor of 30 over results predicted from a linear damage rule. The Damage Curve Approach of Manson and Halford was used to predict this nonlinear cumulative behavior.

This book was released on 1962 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of compressive loads on structural fatigue at elevated temperatures are investigated using plain, notched, and welded Titanium 8Al-1Mo-1V, and PH 15-7Mo stainless steel coupon specimens. Specimens are subjected to Mach 3 spectrum test environment, including compressive loads. Fatigue life predictions are compared with spectrum teset results. The influence of prior stress-strain history on subsequent life is considered. Prediction methods are extended to include the compression range, and results notched specimens is determined analytically and experimentally. A variety of individual variable fatigue tests are performed at temperatures up to 900F.

Book excerpt: In Hansons Marathon Method, the coaches of the Hansons-Brooks Distance Project reveal the methods they've used to turn their runners into race winners, national champions, and Olympians. Hansons Marathon Method offers a radical overhaul of marathon training that promises to turn any runner into a true marathoner and help experienced marathoners set new personal bests. Hansons Marathon Method does away with mega-long runs and high-mileage weekends--two outdated traditions that make most runners miserable. Instead, runners using the Hansons method will gradually build up to the moderate-high mileage required for marathon success, spreading those miles more sensibly throughout the week. Running easy days mixed with precisely paced speed, strength, and tempo workouts, runners will steel their bodies and minds to run the hardest miles of the marathon. Both Beginner and Advanced training programs feature the unique Hansons 16-mile long run which, as part of the Hansons program, is ideal for preparing the body for the marathon. Humphrey explains how runners should set their goal race pace and shows how to customize the Hansons method to their own needs, like adding extra racing, running more miles, and handling training interruptions. Detailed nutrition and hydration chapters help runners pinpoint their personal energy and hydration needs so they know precisely how much to eat and drink during workouts, race week, race day, and for recovery. The Hansons approach to pacing and nutrition means marathoners will never hit the wall. Hansons Marathon Method lays out the smartest marathon training program available from one of the most accomplished running groups in the nation. Using this innovative approach, runners will mold real marathon muscles, train their body to never hit the wall, and prepare to run their fastest marathon.

Download or read book Fatigue of Materials and Structures written by Claude Bathias and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of mechanical structures with predictable and improved durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading researchers in the field, this book, along with the complementary books Fatigue of Materials and Structures: Fundamentals and Application to Damage and Design (both also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. This book deals with multiaxial fatigue, thermomechanical fatigue, fretting-fatigue, influence of defects on fatigue life, cumulative damage and damage tolerance, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of materials science and engineering, mechanical, nuclear and aerospace engineering.
