Sentence examples for scratch deformation from inspiring English sources
The ability to design polymers with good scratch visibility resistance requires extensive knowledge about scratch deformation mechanisms and their propensity for light scattering.
The resistance to scratch deformation is discussed in terms of tensile modulus, elastic recovery, scratch hardness, and reinforcement matrix interaction.
The surface damage behavior during scratch deformation of neat and wollastonite reinforced ethylene propylene and polypropylene polymeric materials with significant differences in ductility was studied using electron microscopy in association with scratch deformation parameters and local crystallinity characteristics obtained from atomic force microscopy.
In this work, a third option is explored: using a long working distance optical microscope alongside a commercial scratch tester to allow oblique observation of scratch deformation with sub-micrometer resolution during scratching.
The scratch deformation map described indicates that there is a major change in the deformation mechanism as the exposure time proceeds and this is related first to a sample plasticization and then to a restructuring process of the PMMA methanol system due to the greater mobility and relaxation of the polymer molecules as they imbibe the solvent.
After scratching, plastic deformation occurred on the scratched area and a groove with residual depth of 1.1 nm was generated.
A three-dimensional finite element method modeling along with experimental study on multilayer acrylic coating systems on a hard and brittle substrate has been performed to understand their scratch-induced deformation and damage mechanisms.
A 3-D finite element method (FEM) modeling was conducted to further understand the observed scratch-induced deformation in the model systems.
Attenuated total reflectance Fourier transform infrared spectroscopy, atomic force microscopy, COF measurement, uniaxial tensile and compressive true stress-strain curves generation, and dynamic mechanical analysis (DMA) were carried out to link intrinsic material properties to the observed scratch-induced deformation mechanisms of the model CPU systems.
Increased doses of antibiotics and increased duration of elution may also decrease the hardness of polymethyl methacrylate (PMMA) bone cement, thus increasing the chances of shattering, scratching, and deformation.
Although extending the elution process allows for more antibiotics to elute, via the pores in the matrix and along the surface, it is not enough to demonstrate that the cement is more prone to shattering, scratching, or deformation.
