This book was released on 1982 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report contains recent developments in three aspects of joints in advanced fibrous composite structures: (1) nonlinear analysis of adhesively- bonded stepped-lap joints and doublers, (2) multirow mechanically fastened joints in aerospace structures, and (3) nonlinear analysis of combined bonded and bolted joints. The methods developed include nonlinearities needed for metal structures as well as those for composites. The analysis are based on continuum mechanics techniques and have been coded into three Fortran IV digital computer programs A4EI, A4EJ, and A4EK respectively. The report contains explanations of the derivations of the solutions as well as sample worked problems to illustrate both the capabilities of the programs and the behavior characteristics of the real structures.

Book excerpt: In the analysis and design of bonded and bolted composite joints, certain input data are required that are not readily available. Many engineering hours at the depots are expended in obtaining the required information. Even when the data are obtained, the accuracy of it is sometimes questionable. The availability of this information in a computerized database would greatly facilitate composite joint analysis and design. The work described in this report involved an extensive search of the technical literature for adhesive and composite material property data as well as bonded and bolted joint properties. The data collected in the literature search were tabulated into a user friendly format for ready retrieval. The data in this tabulation include, in addition to material properties, discussions of fastener and joint design parameters, loading and environmental effects and test methods.

Download or read book Mechanics of Hybrid Bonded bolted Joints written by Kobyé Bodjona and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Large mechanical structures, for example aircraft and motor vehicles, usually consist of a number of subassemblies. This necessitates the use of joints, which locate the subassemblies and transfer loads between them. While necessary, joints introduce discontinuities into the structure that act as stress raisers and regions of possible failure initiation. Consequently, joint design is crucial for achieving satisfactory structural strength.Joining composite structures is all the more challenging compared to metallic structures. This is due to the brittle nature of many composite materials, which permits only modest plastic deformation and limits the corresponding mitigation of stress concentrations prior to fracture. This is particularly problematic for bolted composite structures. In order to fully exploit the potential of composites, it is thus necessary to develop more efficient means of joining them. In recent years, several investigators have shown experimentally that a combination of bonding and bolting can, sometimes, produce a joint that is stronger than either of these joints by itself. This could potentially result in a more efficient joint and is therefore of particular interest for composite structures. These investigators found that load sharing between the adhesive and bolt is important for achieving the benefits of "hybridization". However, they had only limited understanding of the most effective way to achieve load sharing. Furthermore, they made no attempt to predict the strength of hybrid joints by means of mathematical modelling.In response to these shortcomings in the literature, this thesis follows a two-pronged approach. First, in Chapters 3-4, load sharing in hybrid bonded-bolted joints is addressed. An efficient numerical model is developed in Chapter 3 for this end. This model is validated experimentally, after which it is used in a global sensitivity analysis in Chapter 4 to determine the most important factors influencing load sharing. Of the various parameters considered, it is found that the adhesive yield strength, overlap length and adhesive hardening modulus have the greatest effects, by a considerable margin.Next, in Chapters 5-10, strength is addressed. For this purpose, an original mathematical model of a hybrid bonded-bolted joint is developed from first principles. This model distills the physical problem to the essentials, yet accounts for many complex effects found in real joints. Through comparison with the experimental results presented in Chapter 10, the model is shown to be capable of providing a basic prediction of bonded-, bolted-, and hybrid-bonded-bolted joint strength. Agreement to within 8% of the experiment is demonstrated. The model is subsequently used to elucidate key behaviours of hybrid bonded-bolted joints in Chapter 11.Based on the findings of this thesis, increased confidence has been established in the feasibility of the hybrid bonding-bolting concept. Furthermore, the developed analysis methodology has demonstrated significant promise for use as part of a design tool." --
