TLDR
In this paper, an integrated analysis approach is proposed to seek a better understanding of the scratch damage of polymers, which essentially involves the use of a new scratch test device for testing, employing microscopy techniques and image an analysis tool, VIEEW®, for studying material damage and scratch visibility, and finally, performing finite element (FE) modeling to examine the mechanical response of the polymeric substrate involved during the scratch process.Abstract:
To seek a better understanding of the scratch damage of polymers, an integrated analysis approach is proposed in this article. This integrated approach essentially involves (a) the use of a new scratch test device for testing, (b) employing microscopy techniques and image an analysis tool, VIEEW®, for studying material damage and scratch visibility, and finally (c) performing finite element (FE) modeling to examine the mechanical response of the polymeric substrate involved during the scratch process. Applying this approach to five model material systems and employing linearly increasing load tests, the findings of the fundamental material science study of the scratch damage of these materials are presented. From the three-dimensional FE analysis, the numerical results generated were able to reasonably predict the scratch damage and provide corresponding mechanistic interpretation. The essential link between material science and mechanics outlines the uniqueness of this approach for studying the scratch damage of polymers.read more

Understanding and quantification of elastic and plastic deformation during a scratch test
TL;DR: In this paper, the authors measured the normal and tangential scratch forces, the penetration depth relative to the initial surface and the three-dimensional topographic relief of the scratched surface, and used these parameters to accurately calculate the actual contact area between the indenter and the material, taking into account both elastic deformation and pile-up phenomena.

Scratching maps for polymers
TL;DR: In this paper, a review of the application of scratch maps for polymers is presented, where the scratch hardness and deformation mechanisms for a poly(methylmethacrylate) (PMMA), a poly (tetrafluoroethylene) (PTFE), and an ultra-high molecular weight poly(ethylene), as well as the deformation mechanism is determined by the most efficient energy dissipation process for particular external constraints.

Analytical models of scratch hardness
TL;DR: The ability of one material to abrade or scratch another has a long history as the basis of a scale of hardness and is clearly related to the now more common measure of hardness as the resistance of a material to indentation as discussed by the authors.
