Available in PDF, EPUB and Kindle. Book excerpt: This report describes a formal method to quantify structural damage tolerance and reliability in the presence of a multitude of uncertainties in turbine engine components. The method is based at the material behavior level where primitive variables with their respective scatter ranges are used to describe behavior. Computational simulation is then used to propagate the uncertainties to the structural scale where damage tolerance and reliability are usually specified. Several sample cases are described to illustrate the effectiveness, versatility, and maturity of the method. Typical results from this method demonstrate that it is mature and that it can be used to probabilistically evaluate turbine engine structural components. It may be inferred from the results that the method is suitable for probabilistically prediciting the remaining life in aging or deteriorating structures, for making strategic projections and plans, and for achieving better, cheaper, faster products that give competitive advantages in world markets.

This book was released on 2013-10-22 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full-scale Fatigue Testing of Components and Structures presents the approaches to the testing of full-scale components or structures. The book begins by examining the necessity or desirability of full-scale fatigue testing. Subsequent chapters are devoted to the discussion of fatigue testing done on aircraft structures, railway components, helicopter rotor heads, artillery gun structures, and bridge components. The role of full-scale fatigue testing on automotive components and systems, structural testing in nuclear engineering, and the use of a structural fatigue testing laboratory for other tests are covered as well. Engineers, materials scientists, and researchers in the field of fatigue testing will find the book very useful.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Air Force has initiated a technology development initiative known as Engine Rotor Life Extension (ERLE), which has the goal of extending the useful lifetime of major, fracture-critical components in currently fielded gas turbine engines, without increasing the risk of component failure. Full achievement of this goal will require improvements in a broad range of technologies, including life prediction and fracture mechanics, nondestructive evaluation, engine usage and health monitoring, and component repair. This paper focuses on a key aspect of the life prediction process - the incorporation of residual stress effects. The benefits of compressive residual stresses in improving fatigue life, retardation of crack growth and resistance to foreign object damage have been demonstrated. Hence, the%se beneficial surface treatments are extensively employed in the turbine engine components. However, current damage-tolerance-based life management practices do not explicitly account for the residual stresses induced by surface enhancement procedures. Significant increase in predicted damage tolerance can be obtained if residual stresses are included in the life prediction methodology. This paper provides an assessment of the role of residual stresses in the durability of the component and identifies critical issues to be addressed during implementation in life prediction methods.

Available in PDF, EPUB and Kindle. Book excerpt: This book discusses several mechanical and material problems that are typical for gas turbine components. It discusses accelerated tests and other methods for increasing the reliability of gas turbine engines. Special attention is given to non-traditional methods for calculating the strength characteristics and longevity of the main components. This first volume focuses on the selection of materials, deformation and destruction mechanisms in connection with stationary and non-stationary loading, and types of material damage such as the thermal fatigue. Particular attention is paid to the issues of the properties of single crystal alloys, the relationship between structure and properties, the influence of technological factors and long-term operation. The characteristics of creep resistance, crack resistance, and resistance to cyclic deformation of different alloys are given.
