Book Synopsis Fatigue and Fracture of Adhesively-Bonded Composite Joints by : Anastasios P. Vassilopoulos
Download or read book Fatigue and Fracture of Adhesively-Bonded Composite Joints written by Anastasios P. Vassilopoulos. This book was released on 2014-10-21. Available in PDF, EPUB and Kindle. Book excerpt: It is commonly accepted that the majority of engineering failures happen due to fatigue or fracture phenomena. Adhesive bonding is a prevailing joining technique, widely used for critical connections in composite structures. However, the lack of knowledge regarding fatigue and fracture behaviour, and the shortage of tools for credible fatigue design, hinders the potential benefits of adhesively bonded joints. The demand for reliable and safe structures necessitates deep knowledge in this area in order to avoid catastrophic structural failures. This book reviews recent research in the field of fatigue and fracture of adhesively-bonded composite joints. The first part of the book discusses the experimental investigation of the reliability of adhesively-bonded composite joints, current research on understanding damage mechanisms, fatigue and fracture, durability and ageing as well as implications for design. The second part of the book covers the modelling of bond performance and failure mechanisms in different loading conditions. - A detailed reference work for researchers in aerospace and engineering - Expert coverage of different adhesively bonded composite joint structures - An overview of joint failure

Book Synopsis Mechanics of Bi-material Beams and Its Application to Mixed-mode Fracture of Wood-FRP Bonded Interfaces by : Cole S. Hamey
Download or read book Mechanics of Bi-material Beams and Its Application to Mixed-mode Fracture of Wood-FRP Bonded Interfaces written by Cole S. Hamey. This book was released on 2007. Available in PDF, EPUB and Kindle. Book excerpt: In this study, mechanics models for bi-layer beams suitable for bi-material interface characterization are introduced, and their application to mixed mode fracture of wood-FRP bonded interface is studied. First, an engineering approach for evaluating the mixed-mode (Mode-I/II) fracture toughness of wood/FRP composite bonded interfaces is presented. Two four-point bending specimens, i.e., four-point asymmetric end-notched flexure (4-AENF) and fourpoint asymmetric mixed-mode bending (4-AMMB), are proposed for the study of the mixed-mode fracture. With proper design, the rate of compliance change with respect to crack length can be determined to be independent of the crack length for the specimens. The proposed specimens can be used to determine the mixed-mode fracture toughness without the need of measuring the crack propagation length. Mode decompositions are evaluated for each specimen, and with previously determined Mode-I and Mode-II data, a number of failure criteria and failure envelopes are determined for the wood-FRP interface. Second, an intuitive mechanics-based approach is presented to analyze layered beams using the split beam model, from which the layered beam is modeled as individual subbeams and the stress acting throughout each sub-beam is used to determine the forces acting on the sub-beams. The split beam model is adapted to evaluate the compliance and ERR of three common groups of fracture specimens and loading conditions: Mode-I dominant (ADCB and DCB), Mode-II dominant (AENF and ENF), and Mixed-Mode (ASLB and SLB). It is demonstrated that the split beam model generates solutions consistent with those of existing specimens found in literature. Also, derived specimens are provided to allow for different ways of viewing the specimen configurations and possible ways of applying loads to achieve certain conditions. The compliance and ERR of two derived specimens are presented. The ERR for these two specimens is shown to be the same as the existing solutions, thus validating the accuracy of the approach. The simplified bi-layer models and related application to fracture of bi-material interface introduced in this study improve the data reduction techniques in fracture characterization and facilitate analysis and design of bi-material fracture specimens.
