Indentation Depth Dependent Mechanical Behavior in Polymers [PDF]
Various experimental studies have revealed size dependent deformation of materials at micro and submicron length scales. Among different experimental methods, nanoindentation testing is arguably the most commonly applied method of studying size effect in

Effect of Indenter Load on Vickers Microhardness and Indentation Depth of One Resin Composite. [PDF]
The load and size of the indentation may affect the hardness value. This study investigated the effect of the indentation size on the microhardness of one resin-based composite (RBC). Metal molds 4 mm deep and 12 mm in diameter were filled with Tetric EvoCeram Bulk Fill (Ivoclar) and light-cured for 10 s using a broad-spectrum LED curing light.

Analysis of depth-sensing indentation tests with a Knoop indenter [PDF]
The present work shows how data obtained in a depth-sensing indentation test using a Knoop indenter may be analyzed to provide elastic modulus and hardness of the specimen material. The method takes into account the elastic recovery along the direction of the short axis of the residual impression as the indenter is removed.

The neural signal for skin indentation depth. I. Changing indentations [PDF]
Psychophysical tests on human subjects showed that judgments of skin indentation depth made when the fingertip was indented at rates from 0.2 to 16 mm/sec were quite insensitive to changes in indentation velocity. Similar results were obtained on the forearm at indentation velocities of 0.4 to 16 mm/sec.

The neural signal for skin indentation depth. II. Steady indentations [PDF]
The glabrous skin of the monkey's hand was stimulated with a waveform that indented the skin at a rate of 0.4 mm/sec, held the skin steadily or nearly steadily indented for 12 sec or longer, and then retracted back to the starting position. Recordings were made of activity in single afferent fibers in response to these stimuli.

Indentation Characteristic Strain Determined Based on Metallic Material Damage [PDF]
Characteristic strain is a key parameter connecting the hardness and flow stress for indentation experiments. However, there are significant difference between the characteristic strains obtained from previous models.
