Atomic force microscopy (AFM) has been widely used in materials science and chemistry
research since it was invented in the 1980s. It is a relatively new tool for geosciences and is …

This paper aims to discuss the recent development in rock hardness testing methods and
their applications in rock engineering and geological studies. Hardness is one of the …

The work presented in this thesis was developed at the Department of Civil Engineering of
University of Minho. This work is eminently experimental and intends to be a valuable …

The effect of the surface roughness on nanoindentation results was investigated instancing
a series of CrN thin films deposited by unbalanced magnetron sputtering. The arithmetic …

Surface roughness is a commonly used criterion for characterization of surface quality in a
machining operation. In the study of micro-scale mechanical properties of machined surface …

Using a compilation of experimental results obtained on different materials, the influence of
the average roughness Rms on the precision σE (standard deviation) of the Young's …

This paper is focused on the identification of a relation between surface hardening and
roughness induced by ultrasonic shot peening. A method that dissociates the influence of …

Indentation with a spherical indenter tip into CrN coatings with an arithmetic surface
roughness (Ra) ranging between 2.6 and 11.1 nm is modelled with the finite element …

Nanoindentation is a popular tool for the study of hardness and elasticity of materials at the
nanoscale. However, the roughness of such samples may violate the basic assumptions …

When nanoindentation is used for thin film characterization, the penetration of the indenter is
usually limited to shallow indents to avoid the spurious effect of the substrate. However, the …
