Available in PDF, EPUB and Kindle. Book excerpt: This paper describes the analytical/experimental correlation study performed to develop an understanding of the behavior of notched boron/epoxy laminates subjected to tension/tension fatigue loading. The static failure analysis of notched laminates used herein treats the following modes of failure: axial cracking in the load direction, and transverse cracking across the specimen. The "mechanistic wearout" fatigue analysis uses this static failure model and embodies the concept that material properties in the notch region are continually changing with cyclic loading and that, if these properties are known at a given time, they could be used in the static failure analysis to compute residual strength and preferred mode of crack propagation. In order to verify the fatigue model, an experimental program of limited scope was undertaken to obtain boron/epoxy lamina static and fatigue data (longitudinal and transverse tension and in-plane shear), unnotched [02/±45]s laminate static data, and notched [02/±45]s laminate static and fatigue data. Laminate fatigue behavior was determined from lamina fatigue data, and analysis predictions were compared with the notched-laminate fatigue data. The specific phenomena of interest are the initiation of fatigue damage and its growth as a function of load cycles, fatigue life and mode of failure, and the residual strength after a predetermined number of cycles and the corresponding mode of failure. Certain predicted phenomena such as the increase in residual strength after fatigue loading and both axial and transverse damage growth were observed experimentally. However, correlation of theory and experiment was hampered by the following factors: delamination of the 0-deg surface layers in the region of the longitudinal projection of the notch diameter, lack of statistically significant data base for lamina fatigue properties in general, and absence of lamina axial compression fatigue data in particular. The principal deficiency appears to be the lack of a capability to predict growth of delaminations. Therefore, the interplay of stacking sequence and various failure modes needs to be investigated analytically and experimentally in detail.

Book excerpt: Structural Analysis Systems: Software—Hardware Capability—Compatibility—Applications, Volume 2 is a practical guidebook on structural analysis systems and their applications. It provides detailed information about a specific software, its postprocessor capabilities and limitations, computer-aided design connection, and compatibility with the most common computers. Several practical examples from industry with computer and user cost are given. This volume consists of 17 chapters and begins with a description of AFAG, a dual finite element analysis program based on the flexibility method. The discussion then turns to the AQUADYN system, designed primarily to reduce the hydrodynamics problem to a linear integral equation for large floating or immersed structures. The following chapters focus on other structural analysis computer programs such as BOSOR4 and BOSOR5, INFESA, MEF/MOSAIC, RCAFAG, and STRUGEN. Some general purpose and special purpose finite element programs used for stress analysis of composite materials are also considered. This book will be a useful resource for practitioners in scientific and industrial disciplines such as mechanical or civil engineering, informatics, applied mathematics, and computer science.

This book was released on 1983 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is Vol. I of a 2-part final report on the activities which were conducted under Contract No. F33615-81-3225. The general objective of this program was to investigate the precise nature of the damage events caused by cyclic (fatigue) loading of composite laminates that are directly related to fracture of those laminates, to develop a conceptual understanding of how those damage events reduce the residual strength of the laminates, and to determine how the collective damage condition following long-term cyclic loading precipitates the final fracture event. The program was conducted in four phases: (1) the development of fatigue damage during long-term cyclic loading was investigated in such a way that the damage events which occur quite late in the fatigue life of the material, just prior to fracture, were identified and characterized; (2) the special contribution and nature of fiber fracture was investigated; (3) the nature of the collective damage condition which precipitates the fracture event under long-term fatigue loading was investigated; (4) a philosophy of fracture in composite laminates following severe damage development due to cyclic loading was developed. A wide variety of destructive and nondestructive experimental evaluation schemes were used in the program, and several analytical efforts were conducted to support the experimental activities.

Available in PDF, EPUB and Kindle. Book excerpt: From the Author's PrefaceThe objective of this book is to provide a thorough and systematic study of the problem of laminated composites containing stress concentrations. Stress concentrations are introduced in laminated plates in the forms of circular holes, elliptical openings and straight cracks. These forms of cutouts have many practical applications, and are familiar to most engineers. Stress concentrations exist in all known structural components. Stress concentrations have great practical importance because they are normally the cause of failure. In addition to stress analyses of laminated composites, we need more fundamental understanding of the failure mode, the failure criterion, the effects on global laminate response, and the design of composites in the presence of stress concentrations. In this book, all the subjects studied are closely related to the problem of stress concentrations in laminated composites . . . . All the models are verified with many experimental results. The underlying objective of this comprehensive study is to give the readers an in-depth and thorough understanding of the problem of stress concentrations in composites. This book is the first to address the problem of laminated composites containing stress concentrations in a systematic way.

This book was released on 1981 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical and experimental studies of identify the dominant failure mechanisms for compression fatigue of notched composite laminates have been conducted. The effects of stacking sequence and matrix material on damage growth as well as failure mechanisms under compression fatigue loading are reported. Two types of resin materials and four kinds of laminate layups have been considered. Two of the stacking sequences are fiber dominated and two are quasi-isotropic. Ultrasonic C-scans and photomicrographic studies have been utilized for experimental observations. An analytical methodology developed for the study of tension fatigue of notched laminates has been modified to obtain patterns of damage growth under quasi-static load by increasing it gradually in steps. For each step increase in load, a finite element stress analysis is performed and intralaminar and/or interlaminar failures in the elements are predicted.
