Indentation Depth Dependent Mechanical Behavior in Polymers [PDF]

open access: yesAdvances in Condensed Matter Physics, 2015
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

The neural signal for skin indentation depth. I. Changing indentations [PDF]

open access: yesThe Journal of Neuroscience, 1983
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.

The neural signal for skin indentation depth. II. Steady indentations [PDF]

open access: yesThe Journal of Neuroscience, 1983
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.

Shape Effects of Indenter on the Depth-Sensing Indentation

open access: yesAdvanced Materials Research, 2010
It is revealed that the conventional reduced modulus used in depth-sensing indentation tests is invalid for a flat-ended cylindrical indenter due to the fact that the contact area during the loading is a constant irrelative to load. The load-displacement

The Analysis of Depth-Sensing Indentation Data

open access: yesMRS Proceedings, 1993
Common methods for analyzing depth-sensing indentation data are briefly reviewed and an overview of the principal factors limiting the accuracy and precision of results obtained using these methods is presented.

SMALL DEPTH INDENTATION OF UHMW (POLYETHYLENE)

open access: yesTransactions of the Canadian Society for Mechanical Engineering, 1995
Indentation tests based on the local deformation of UHMW-Polyethylene plastic material by harder indenters were conducted using a designed apparatus which detects precisely the first contact between the tip of the indenter and the sample.

Effects of Surface Stress on the Load-Depth Curves of Depth-Sensing Indentation

open access: yesMRS Proceedings, 2004
Based on the effects of residual surface stress on the unloading curves of indentation load-depth responses, an experimental scheme for determination of the residual stress by depth-sensing indentation is proposed.

Effect of Indenter Load on Vickers Microhardness and Indentation Depth of One Resin Composite. [PDF]

open access: yesMaterials (Basel)
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]

open access: yesJournal of Materials Research, 2001
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.

Role of indentation depth and contact area on human perception of softness for haptic interfaces. [PDF]

open access: yesSci Adv, 2019
In engineering, the "softness" of an object, as measured by an indenter, manifests as two measurable parameters: (i) indentation depth and (ii) contact area. For humans, softness is not well defined, although it is believed that perception depends on the
