This thesis presents the results of a study into the mechanics of stresses in adhesive layer and the failure of adhesively bonded lap joints. A brief survey was made of the existing methods on the stress analysis of adhesively bonded lap joints. Following this is a discussion of the mechanics of adhesively bonded lap joints. The existence of stresses and factors affecting these stresses are presented in physical terms. A new method is presented for the determination of bending moments at the ends of the overlap for single lap joints. This method is accurate for joints with either identical or different adherends. A new procedure combining the analytical and numerical methods was proposed to obtain stresses in the adhesive layer accurately and efficiently. The reason why analytical methods yield somewhat hall the real peel stresses in the adhesive layer in double lap joints has been establis'hed. Some improvements in the determination of peel stresses in the adhesive layer in double lap joints have been made. A three dimensional stress analysis was carried out to study the stress distribution across the joint- width. An intuitive and numerical study was made into the mechanics of the longitudinal stresses in the adhesive layer. An elastic-plastic stress and strain analysis. has been performed with FEM on joints bonded with radii adherends to study the effect of the rounding of the adherend corners on the stress distribution in the adhesive layer. Some study into the failure process and failure modes were performed. Tests were made on both double and single lap joints. Finally. the failure criteria concerning strength predictions of adhesively bonded joints were reviewed. A, new criterion was proposed for the prediction of joint strength

The purpose of this study is to determine how early man fastened wood together in order that it might be utilized to a greater extent and to trace the improvements and additions which have been made in these original fasteners of wood in the ensuing years.

Yes / The torque-tension relationship of threaded fasteners affects almost all engineering disciplines. Tribological processes at fastener interfaces manifest as the system's friction coefficient. Lubrication-related influences are usually described empirically using K or μ. The drive towards lightweight fastener materials in engineering systems and lubricants with reduced environmental impact is challenging existing knowledge and industrial practice in a range of applications, many safety critical. More comprehensive understanding is needed to achieve repeatable friction during assembly and re-assembly, resistance to loosening and fretting during operation, and effective anti-seize for disassembly with a growing range of materials and lubricants. The lubricants considered showed three predominant lubrication mechanisms: plastic deformation of metal powders; burnishing/alignment of molybdenum disulphide, MoS2; and adhering/embedding of non-metal particles. Multivariate analysis identified key sensitivities for these mechanisms. Assembly generated changes at fastener surfaces and in the lubricating materials. Re-assembly exhibited significant reductions in friction. / The full-text of this article will be released for public view at the end of the publisher embargo on 07 Dec 2024.
