A mechanistic framework to differentiate nanoindentation-induced plasticity and fracture in layered materials

Communications Materials
During nanoindentation of layered materials, a plethora of deformation mechanisms manifest in the load-displacement data as discrete displacement bursts, whose physical origins are often difficult to isolate from indentation data alone.

The Macroscopic Stress–Macroscopic Strain Relationship of the Hierarchical Honeycomb Nanoporous Materials by the Spherical Nanoindentation Simulation

Nanomaterials
The spherical nanoindentation macroscopic stress–macroscopic strain relationship of hierarchical honeycomb nanoporous material is defined by combining the spherical nanoindentation simulation and the uniaxial compression simulation. At the same time, the

Substrate effect in the evaluation of elastic modulus of thin PVD coatings from nanoindentation

Acta Polytechnica CTU Proceedings
The comparison of nanoindentation results on reactive HiTUS TiZrHf+ME-Ny (ME = Nb, V, Ta and VNbTa) and reactive DCMS NbMoTaW coatings showed that the influence of substrate stiffness is still not fully eliminated in the evaluation of indentation ...
