The Calibration of the Nanoindenter
MRS Proceedings, 1993The nanoindenter has a tremendous potential for the measurement of mechanical properties of thin films and coatings. Information can be obtained about plastic, elastic and time dependent deformation behaviour. In some cases fracture behaviour of the coatings and the adhesion of the coating to the substrate can also be investigated.Before accurate and ...

Surface Effects on Nanoindentation [PDF]
Journal of Materials Research, 2002 In this paper, we report on a study of the surface effect on nanoindentation and introduce the apparent surface stress that represents the energy dissipated per unit area of a solid surface in a nanoindentation test. The work done by an applied indentation load contains both bulk and surface work.

Nanoindentation and storage of teeth
Journal of Biomechanics, 2002This study determined changes in nanomechanical properties of dentin and enamel during storage in deionized water, calcium chloride buffered saline solution and Hank's balanced salts solution (HBSS). Atomic force microscopy based nanoindentation showed that storing teeth in deionized water or CaCl(2)-solution resulted in a large decrease in elastic ...

Small-scale polymers are increasingly being applied to a variety of fields, making it important to understand the behavior of polymers at small length scales. Indentation size effects (ISE) is the apparent increase in material-specific properties at very low indentation depths.

Nanoindentation of dental composites
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005AbstractThe intent of this project was to evaluate the elastic modulus and hardness of four composites with different fillers, a microfill, a hybrid, a dental resin cement, and a fiber filler, using nanoindentation. An indentation load of 0.001 N was used and 100 indents per specimen were taken. The elastic modulus measured for the Choice composite was

Reverse Plasticity in Nanoindentation [PDF]
MRS Proceedings, 2007 AbstractThis paper summarises our recent cyclic nanoindentation experiment studies on a range of materials including single crystal and nanocrystalline copper, single crystal aluminium and bulk metallic glasses with different glass transition temperatures. The unloading and reloading processes of the nanoindentation curves have been analysed.

A range of mechanical properties of a coating/substrate system may be obtained using indentation tests, and with the emergence of continuously recording indentation testing with nanometre penetration (often called nanoindentation) the mechanical properties of very thin coatings (

Applications of Nanoindentation
2004Nanoindentation finds a wide application. The test results provide information on the elastic modulus, hardness, strain-hardening, cracking, phase transformations, creep, fracture toughness, and energy absorption. Since the scale of deformation is very small, the technique is applicable to thin surface films and surface modified layers.

Nanoindentation of natural diamond
Philosophical Magazine A, 2002Abstract This study demonstrates that the plane-strain Young's moduli E* = E/(1 - v 2) of natural diamonds with a weight of less than 0.2 carat can be determined by the technique of nanoindentation, where E is Young's modulus and v is Poisson's ratio. The indentation test with a Berkovich indenter was conducted at loads of 50, 100 and 300 mN for three ...

Time-Dependent Nanoindentation
2004In general, materials can resist deformation in a solid-like or viscous-like manner. Solid-like materials store energy under deformation, and upon removal of stress, returns to its original state. Viscous materials dissipate energy during deformation and upon removal of stress, remains in its deformed state.
