ESTIMATION OF EFFECTS OF INDENTER-TIP GEOMETRY BY MEANS OF FINITE ELEMENT ANALYSIS OF NANO-INDENTATION
Abstract
To investigate the influence of geometric error of indenter tip in nano-indentation test, direct measurement of indenters and analyses of indentation process are carried out. Geometry of indenter tip is measured with a scanning probe microscope and geometrical parameters such as face angles, tip radius and truncation length are calculated. Based on these results, the models for the finite element analyses are created. Analyses of indentation processes into a metal sample are carried out and the influence of tip geometry is discussed.
