INFLUENCING THE INDENTATION CURVES BY THE BLUNTNESS OF THE BERKOVICH INDENTER AT THE FEM MODELLING

Acta Polytechnica CTU Proceedings, 2020
The influence of the Berkovich indenter bluntness on the indentation curves at nanoindentation test of fused silica is determined by the FEM (finite element method) in this paper. The Berkovich indenter, which is mostly used for the nanoindentation test,

Evaluating local strain rate sensitivity of titanium alloy using dynamic nanoindentation testing

Measurement: Sensors, 2021
Constant strain rate nanoindentation testing is useful for evaluating local strain rate sensitivity. In titanium alloys, the dwell fatigue at room temperature is a critical issue, and this phenomenon is known as relating to local strain rate sensitivity.

Measuring the effect of residual stress on the machined subsurface of Inconel 718 by nanoindentation.

PLoS ONE, 2021
Inconel 718 alloy is widely used in aero-engines and high-temperature environments. However, residual stress caused by processing and molding leads to an uneven distribution of internal pressure, which reduces the reliability of service process ...
