Available in PDF, EPUB and Kindle. Book excerpt: This timely book on structural adhesives joints showcases all the pertinent topics and will be of immense value to scientists and engineers in many industries. Most structures are comprised of a number of individual parts or components which have to be connected to form a system with integral load transmission path. The structural adhesive bonding represents one of the most enabling technologies to fabricate most complex structural configurations involving advanced materials (e.g. composites) for load-bearing applications. Quite recently there has been a lot of activity in harnessing nanotechnology (use of nanomaterials) in ameliorating the existing or devising better performing structural adhesives. The 10 chapters by subject matter experts look at the following issues: Surface preparation for structural adhesive joints (SAJ) Use of nanoparticles in enhancing performance of SAJ Optimization of SAJ Durability aspects of SAJ Debonding of SAJ Fracture mechanics of SAJ Failure analysis of SAJ Damage behavior in functionally graded SAJ Impact, shock and vibration characteristics of composites for SAJ Delamination arrest methods in SAJ

Available in PDF, EPUB and Kindle. Book excerpt: This volume documents the proceedings of the International Symposium on Adhesive Joints: Formation, Characteristics and Testing held under the auspices of the Division of Polymer Mater ials:Science and Engineering of the American Chemical Society in Kansas City, MO, September 12-17, 1982. There is a myriad of applications (ranging from aerospace to surgery) where adhesives are used to join different materials, and concomitantly the understanding of the behavior of adhesive joints becomes very important. There are many factors which can influence the behavior of adhesive joints, e.g., substrate preparation, in terfacial aspects, joint design, mode of stress, external environ ment, etc., and in order to understand the joint behavior in a holistic manner, one must take due cognizance of all these germane factors. So this symposium was planned to address not only how to make acceptable bonds but their characterization, durability and testing were also accorded due consideration.

Available in PDF, EPUB and Kindle. Book excerpt: Adhesively-bonded joints provide many advantages over conventional mechanical fasteners and are increasingly receiving attention as an alternative to mechanical joints in engineering applications. The traditional fasteners usually result in the cutting of fibers and hence the introduction of stress concentrations, both of which reduce structural integrity. By contrast, bonded joints are more continuous and have potential advantages of strength-to-weight ratio, design flexibility, and ease of fabrication. This book provides an overview of available analytical methods as well as numerical methods.

Download or read book A Fracture Mechanics Approach for Designing Adhesively Bonded Joints written by WS. Johnson and published by . This book was released on 1985 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical and experimental investigation was undertaken to determine if the adhesive debond initiation stress could be predicted for arbitrary joint geometries. The analysis was based upon a threshold total strain-energy-release rate (Gth) concept. Two bonded systems were tested: T300/5208 graphite/epoxy adherends bonded with either EC-3445 or FM-300 adhesive. The Gth for each adhesive was determined from cracked-lap-shear (CLS) specimens by debond initiation tests. Finite-element analyses of various tapered CLS specimen geometries predicted the specimen stress at which the total strain-energy-release rate (GT) equaled Gth at the joint tip. Experiments verified the predictions. The approach described herein predicts the maximum stress at which an adhesive joint can be cycled yet not debond. Total strain-energy-release rate appeared to be the driving parameter for cyclic debonding and debond initiation in structural adhesives, and debond initiation and growth were found to occur with virtually no peel stress present.

Available in PDF, EPUB and Kindle. Book excerpt: Since the advent of synthetic adhesives in the middle of the last century, the growth in their usage has been so phenomenal that a handbook, the International Plastics Selector-Adhesives. published by D.A.T.A. in 1991, lists some 5000 different adhesive formulations that are commercially available. Despite their wide usage, much is not well understood about adhesives and adhesive joint failure. A few observations relevant to this discussion of Fracture Mechanics Analysis of Adhesive Joints are: (a) The stress distribution in such joints is never as simple as often assumed, and the usually reported "standard test results" often completely ignore the most important aspects of the stress distribution. (b) Crack growth does not always initiate at the point of maximum stresses in an adhesive joint. (c) The locus of adhesive crack growth is often somewhat removed from the adhesive-substrate bond-line, but there are instances where it closely follows this bond-line. (d) Adhesive Fracture Mechanics analysis can provide significant information on the resolution of questions raised in these observations. This presentation will review some of the work in these areas by graduate students in our laboratory. Some of the cited work was accomplished by previous lab students. Other parts of the cited work are from ongoing research by current students. The presentation will endeavor to demonstrate that: (a) Adhesive Fracture Mechanics can be used to quantitatively predict the strength of adhesive joints and, more particularly, to elucidate the effects of such factors as adherend thickness, adhesive thickness (and variation), amount of overlap, geometric configuration, material discontinuities, etc. (b) Other factors being equal, crack growth tends to initiate at locations of maximum energy release rate irrespective of whether or not these are points of maximum stresses. (c) The preferred locus of crack growth is along those paths for which the energy release rate is a maximum. In each of these cases, results of a fracture mechanics analysis will be presented along with experimental verification of the analyses.

This book was released on 2012-12-06 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intention of this book is that it should contain everything an engineer needs to know to be able to design and produce adhesively bonded joints which are required to carry significant loads. The advan tages and disadvantages of bonding are given, together with a sufficient understanding of the necessary mechanics and chemistry to enable the designer to make a sound engineering judgement in any particular case. The stresses in joints are discussed extensively so that the engineer can get sufficient philosophy or feel for them, or can delve more deeply into the mathematics to obtain quantitative solutions even with elasto plastic behaviour. A critical description is given of standard methods of testing adhesives, both destructively and non-destructively. The essen tial chemistry of adhesives and the importance of surface preparation are described and guidance is given for adhesive selection by me ans of check lists. For many applications, there will not be a unique adhesive which alone is suitable, and factors such as cost, convenience, produc tion considerations or familiarity may be decisive. A list of applications is given as examples. The authors wish to increase the confidence of engineers using adhesive bonding in load-bearing applications by the information and experience presented. With increasing experience of adhesives en gineering, design will become more elegant as weH as more fitted to its products.
