This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-crystalline polymers have versatile tribological applications and it is of great interest to have a comprehensive understanding of the structure-property relationship, in order to produce better and durable products. This thesis focuses on the anisotropic mechanical responses of oriented semi-crystalline polymer surfaces. A benchmark study with high-density polyethylene (HDPE) highlighted the effect of this induced anisotropy on the viscoelastic behavior studied by a method of contact creep and recovery, and the plastic behavior examined by single-asperity scratching. In this thesis, the relations between microstructure, intrinsic and surface mechanical properties have been investigated. Orientation dependencies of elastic, plastic, and viscoelastic response were analyzed. A new experimental set-up permits the first-time in-situ observation during the contact creep and recovery test on non-transparent surfaces. For friction response, the apparent coefficient of friction was used to characterize the behavior during the contact time, and the geometry of the residual track for the behavior during the lifetime of the track. In conclusion, it is confirmed that the intrinsic properties govern the surface mechanical behaviors. Young's moduli and intrinsic creep compliances dominate the contact creep behaviors. Meanwhile, the scratch responses are largely dictated by the yield behaviors.

Download or read book Mechanical Properties of Solid Polymers written by Ian M. Ward and published by John Wiley & Sons. This book was released on 2012-10-22 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing an updated and comprehensive account of the properties of solid polymers, the book covers all aspects of mechanical behaviour. This includes finite elastic behavior, linear viscoelasticity and mechanical relaxations, mechanical anisotropy, non-linear viscoelasicity, yield behavior and fracture. New to this edition is coverage of polymer nanocomposites, and molecular interpretations of yield, e.g. Bowden, Young, and Argon. The book begins by focusing on the structure of polymers, including their chemical composition and physical structure. It goes on to discuss the mechanical properties and behaviour of polymers, the statistical molecular theories of the rubber-like state and describes aspects of linear viscoelastic behaviour, its measurement, and experimental studies. Later chapters cover composites and experimental behaviour, relaxation transitions, stress and yielding. The book concludes with a discussion of breaking phenomena.
