Is the second harmonic method applicable for thin films mechanical properties characterization by nanoindentation? Is the second harmonic method applicable for thin films mechanical properties characterization by nanoindentation?
G Guillonneau, G Kermouche, J Teisseire +3
The second harmonic method is a dynamic indentation technique independent of the direct indentation depth measurement. It can be used to determine near-surface mechanical propertie…
Influence of fine particles on the stability of a humid granular pile
Xixi Huang, Sandrine Bec, J. Colombani
We have investigated by rotating drum experiments the influence of a small amount of fine particles on the stability of a granular heap. The fine particles are shown to have a stro…
Use of a nanoindentation fatigue test to characterize the ductile-brittle transition
Mathieu Skrzypczak, Christelle Guerret-Piecourt, Sandrine Bec +2
When considering grinding of minerals, scaling effect induces competition between plastic deformation and fracture in brittle solids. The competition can be sketched by a critical…
Electrical charges and tribology of insulating materials
Christelle Guerret-Piecourt, Sandrine Bec, Daniel Treheux
Electrical charges generation occurring during contact and friction of insulating materials has been identified for a long time. However the contribution of these electrical charge…
Effect of hydrostatic pressure on elastic properties of ZDTP tribofilms
Karim Demmou, Sandrine Bec, Jean-Luc Loubet
Previous studies have shown that the elastic properties of Zinc Dialkyl-dithiophosphate (ZDTP) tribofilms measured by nanoindentation increase versus applied pressure (Anvil effect…
Adhesion forces due to nano-triboelectrification between similar materials
Christelle Guerret-Piecourt, Sandrine Bec, Frédéric Ségault +3
Contact electrification and triboelectrification are well-known in the case of dissimilar materials, however the case of charge exchange during friction between nominally identical…
