The relaxed-polar mechanism of locally optimal Cosserat rotations for an idealized nanoindentation and comparison with 3D-EBSD experiments

, 2017
The rotation ${\rm polar}(F) \in {\rm SO}(3)$ arises as the unique orthogonal factor of the right polar decomposition $F = {\rm polar}(F) \cdot U$ of a given invertible matrix $F \in {\rm GL}^+(3)$.

Fluctuating Nonlinear Spring Model of Mechanical Deformation of Biological Particles [PDF]

, 2015
We present a new theory for modeling forced indentation spectral lineshapes of biological particles, which considers non-linear Hertzian deformation due to an indenter-particle physical contact and bending deformations of curved beams modeling the ...

Formation of Intermetallic Sludge Phases in AlMgSi Alloys with High Concentrations of Alloying Elements: A Drawback for Increasing Sustainability

Advanced Engineering Materials, EarlyView.
Sludge phases with brittle fracture behavior form in AlMgSi alloys with high concentrations of alloying elements and negatively influence their ductility. The phase type mainly depends on the Si content and the concentration of minor alloying elements like Fe, Mn, Cr, and Mo strongly influences the number of sludge particles. The need for sustainable

Scale effects of nanomechanical properties and deformation behavior of Au nanoparticle and thin film using depth sensing nanoindentation

Beilstein Journal of Nanotechnology, 2014
Nanoscale research of bulk solid surfaces, thin films and micro- and nano-objects has shown that mechanical properties are enhanced at smaller scales. Experimental studies that directly compare local with global deformation are lacking. In this research,

The elastic-plastic properties of an anti-icing coating on an aluminum alloy: Experimental and numerical approach

Journal of the Mechanical Behavior of Materials, 2021
In this paper, an attempt is made to describe the method that combines the results obtained from nanoindentation experiment with finite element simulation to determine or establish the elastic-plastic properties of a super-hydrophobic anti-icing coating.

Nanoindentation Technique for Characterizing Cantilever Beam Style RF Microelectromechanical Systems (MEMS) Switches [PDF]

, 2005
A nanoindentation technique was used to mechanically actuate a radio frequency micro-switch along with the measurement of contact resistance to investigate its applicability to characterize deflection and contact resistance behaviors of micro-sized ...

Finite-Temperature Quasicontinuum: Molecular Dynamics without All the Atoms [PDF]

, 2005
Using a combination of statistical mechanics and finite-element interpolation, we develop a coarse-grained (CG) alternative to molecular dynamics (MD) for crystalline solids at constant temperature.

On uncertainty of elastic modulus measurements via nanoindentation mechanical testing and conventional triaxial testing

Journal of Rock Mechanics and Geotechnical Engineering
Geomechanical properties of rocks vary across different measurement scales, primarily due to heterogeneity. Micro-scale geomechanical tests, including micro-scale “scratch tests” and nano-scale nanoindentation tests, are attractive at different scales ...
