We derive, using dimensional analysis and finite element calculations, several scaling relationships for conical indentation in elastic-plastic solids with work hardening. Using …
YT Cheng, CM Cheng - Journal of Materials Research, 1999 - Springer
Applying the scaling relationships developed recently for conical indentation in elastic– plastic solids with work-hardening, we examine the question of whether stress–strain …

Using dimensional analysis and finite element calculations we derive several scaling relationships for conical indentation into elastic-perfectly plastic solids. These scaling …
With the advances in instrumented indentation systems and testing methodologies, high speed indentation mapping with indents that take less than a second is now possible. This …
The method we introduced in 1992 for measuring hardness and elastic modulus by instrumented indentation techniques has widely been adopted and used in the …
Instrumented indentation methods, which provide a continuous record of the variation of indentation load, P, as a function of the depth of penetration, h, into the indented specimen …
Y Wei, JW Hutchinson - Journal of the Mechanics and Physics of Solids, 2003 - Elsevier
A continuum theory for elastic–plastic solids that accounts for the size-dependence of strain hardening is employed to analyze trends in the indentation hardness test. Strain gradient …
Indentation is a remarkably flexible mechanical test due to its relative experimental simplicity. Coupled with advances in instrument development, ease of implementation has …
