Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.

Download Fatigue Design Procedures Book in PDF, Epub and Kindle
Fatigue Design Procedures presents the full text of the papers presented at the 4th Symposium of the International Committee on Aeronautical Fatigue held in Munich, Germany on June 16-18, 1965, and summaries of the discussion held about them. The papers featured in the volume covers different aspects of fatigue design. These include fail-safe design for a jet transport airplane, the weapon systems fatigue certification program of the U.S. Air Force, the role of variable amplitude or constant amplitude tests in design studies, the evaluation of allowable design stress and corresponding fatigue life, and the importance of fatigue design testing. This book will be of interest to persons dealing with studies on fatigue design methods.

Aircraft Fatigue: Design, Operational and Economic Aspects contains the proceedings of the ""Symposium on Aircraft Fatigue—Design, Operational and Economic Aspects,"" held in Melbourne, Australia, on May 22-24, 1967. The papers explore the design and operational aspects of the fatigue problem in general aviation and transport aircraft, as well as the economic aspects of the fatigue problem as it affects both operators and manufacturers. This book is comprised of 21 chapters and begins with a description of an approach to structural reliability analysis based on order statistics and the expected time to first failure in a fleet of specified magnitude, along with its application to structures subject to progressive fatigue damage. The following chapters deal with structural load measurement and analysis; design and certification programs for a wide range of aircraft types including the Anglo-French and American civil supersonic transports; acoustic fatigue; and the design of joints. The detection of fatigue cracks in service and the effects of fatigue on the cost of design and operation of aircraft are also discussed. This monograph will be a useful resource for aircraft and aeronautical engineers as well as officials of civil aviation.

Download A Practical Engineering Approach to Predicting Fatigue Crack Growth in Riveted Lap Joints Book in PDF, Epub and Kindle
An extensive experimental database has been assembled from very detailed teardown examinations of fatigue cracks found in rivet holes of fuselage structural components. Based on this experimental database, a comprehensive analysis methodology was developed to predict the onset of widespread fatigue damage in lap joints of fuselage structure. Several computer codes were developed with specialized capabilities to conduct the various analyses that make up the comprehensive methodology. Over the past several years, the authors have interrogated various aspects of the analysis methods to determine the degree of computational rigor required to produce numerical predictions with acceptable engineering accuracy. This study led to the formulation of a practical engineering approach to predicting fatigue crack growth in riveted lap joints. This paper describes the practical engineering approach and compares predictions with the results from several experimental studies.

Download Residual Strength Analyses of Riveted Lap-splice Joints Book in PDF, Epub and Kindle
The objective of this paper was to analyze the crack-linkup behavior in riveted lap-splice joint panels with small multiple-site damage (MSD) cracks at several adjacent rivet holes. Analyses are based on the STAGS (STructural Analysis of General Shells) code with the critical crack-tip-opening angle (CTOA) fracture criterion. To account for high constraint around a crack front, the "plane strain core" option in STAGS was used. The importance of modelling rivet flexibility with fastener elements that accurately model load transfer across the joint is discussed. Fastener holes are not modeled but rivet connectivity is accounted for by attaching rivets to the sheet on one side of the cracks that simulated both the rivet diameter and MSD cracks. Residual strength analyses made on 2024-T3 alloy (1.6-mm thick) riveted lap-splice joints with a lead crack and various size MSD cracks were compared with test data from Boeing Airplane Company. Analyses were conducted for both restrained and unrestrained buckling conditions. Comparison of results from these analyses and results from lap-splice-joint test panels, which were partially restrained against buckling indicate that the test results were bounded by the failure loads predicted by the analyses with restrained and unrestrained conditions.
