Book Synopsis Damage Tolerance of Pressurized Graphite/epoxy Cylinders Under Uniaxial and Biaxial Loading by : Paul A. Lagace
Download or read book Damage Tolerance of Pressurized Graphite/epoxy Cylinders Under Uniaxial and Biaxial Loading written by Paul A. Lagace and published by . This book was released on 1995 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The damage tolerance behavior of internally pressurized, axially slit, graphite/epoxy tape cylinders was investigated. Specifically, the effects of axial stress, subcritical damage, and structural anisotropy were considered including their limitations on a methodology, developed for quasi-isotropic configurations, which uses coupon fracture data to predict cylinder failure. AS4/3501-6 graphite/epoxy cylinders with [90/0/±45]s, [±45/0]s, and [±45/90]s layups were tested in a test apparatus specially designed and built for this work such that pressurization resulted in only uniaxial (circumferential) loading of the cylinders. All cylinders had a diameter of 305 mm and slit lengths ranged from 12.7 to 50.8 mm. Failure pressure was recorded and fracture paths and failure modes evaluated via post-test reconstruction of the cylinders. These results were compared to results from previous tests conducted in biaxial loading. Structural anisotropic effects were further investigated by testing cylinders with the quasi-isotropic [0/±45/90]s layup and comparing these with the results from the other quasi-isotropic [90/0/±45]s layup. In all cases, the failure pressures for the uniaxially loaded cylinders fell below those for the biaxially loaded cases and the methodology was not able to predict these failure pressures. These differences were most marked in the case of the structurally anisotropic cylinders. Differences in fracture paths and overall failure mode were found to be greatest in the cases where there was the largest difference in the failure pressures. Strain gages placed near the slit tips showed that subcritical damage occurred in all cases. These results, coupled with previous work, show that failure is controlled by local damage mechanisms and the subsequent stress redistribution and damage accumulation scenario. It is thus necessary to assess the local effects, such as subcritical damage, while accounting for the influence of global parameters such as axial load and structural anisotropy. Recommendations are made as to work which should be done to better understand such phenomena and thus lead to the establishment of methodologies to better characterize the failure, and thus damage tolerance, of composite materials and their structures. KEY WORDS: Graphite/epoxy, composites, damage tolerance, fuselage, pressurized cylinder.
Book Synopsis Fatigue of Composite Materials by : R. Talreja
Download or read book Fatigue of Composite Materials written by R. Talreja and published by CRC Press. This book was released on 1987 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue in Composites provides extensive contemporary research on fatigue from internationally recognized researchers. Part I introduces the concept, delivering a historical review of the fatigue behavior of fibre-reinforced plastics and illustrating fatigue test methods and fatigue under multiaxial stress systems. Part II reviews current research on micromechanical aspects, emphasizing long-term behavior, interface performance, delamination and damage accumulation. Part III covers the analysis and testing of fatigue behavior. Part IV details physical , micromechanical, computational, statistical, and life-prediction models for constant and variable stress. The final sections offer an overview of the wide range of composite fatigue-related problems experienced by engineers.

Download or read book Fatigue Life Prediction of Composites and Composite Structures written by Anastasios P. Vassilopoulos and published by Woodhead Publishing. This book was released on 2019-10-08 with total page 766 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue Life Prediction of Composites and Composite Structures, Second Edition, is a comprehensive review of fatigue damage and fatigue life modeling and prediction methodologies for composites and their use in practice. In this new edition, existing chapters are fully updated, while new chapters are introduced to cover the most recent developments in the field. The use of composites is growing in structural applications in many industries, including aerospace, marine, wind turbine and civil engineering. However, there are uncertainties about their long-term performance, including performance issues relating to cyclic fatigue loading that hinder the adoption of a commonly accepted credible fatigue design methodology for the life prediction of composite engineering structures. With its distinguished editor and international team of contributors, this book is a standard reference for industry professionals and researchers alike. Examines past, present and future trends associated with the fatigue life prediction of composite materials and structures Assesses novel computational methods for fatigue life modeling and prediction of composite materials under constant amplitude loading Covers a wide range of techniques for predicting fatigue, including their theoretical background and practical applications Addresses new topics and covers contemporary research developments in the field
