Spherical-tip indentation of viscoelastic material
In this paper, the indentation of viscoelastic solids by a spherical-tip indenter is analyzed. The viscoelastic solids are described by a standard solid model, that is, a three-element model. TheExpand

Interfacial toughness measurements for thin films on substrates
Abstract There are more than 200 different methods for measuring adhesion, suggesting it to be material, geometry and even industry specific. This availability has exploded at least partly due to theExpand

Flat‐punch indentation of viscoelastic material
The indentation of standard viscoelastic solids, that is, the three-element viscoelastic material, by an axisymmetric, flat-ended indenter has been investigated theoretically. Under the boundaryExpand

Superhard silicon nanospheres
Abstract Successful deposition and mechanical probing of nearly spherical, defect-free silicon nanospheres has been accomplished. The results show silicon at this length scale to be up to four timesExpand

Non-linear deformation mechanisms during nanoindentation
Abstract Experiments involving the indentation of single crystals of both tungsten and an iron alloy show that the observed yield phenomena can be predicted using a superdislocation model driven byExpand

Brittle‐to‐Ductile Transition in Uniaxial Compression of Silicon Pillars at Room Temperature
Robust nanostructures for future devices will depend increasingly on their reliability. While great strides have been achieved for precisely evaluating electronic, magnetic, photonic, elasticity andExpand

Nanoindentation of Au and Pt/Cu thin films at elevated temperatures
This paper describes the nanoindentation technique for measuring sputter-deposited Au and Cu thin films’ mechanical properties at elevated temperatures up to 130 °C. A thin, 5-nm Pt layer wasExpand

The necessity of both plasticity and brittleness in the fracture thresholds of iron
Abstract In order to explain discontinuous brittle cracking in materials subjected to hydrogen, single-crystal and crack/dislocation simulation studies have been made. The computational scheme allowsExpand
