Abstract

The effect of the elastic deformation of a point-sharp indenter on the relationship between the indentation load P and penetration depth h (P-h curve) is examined through the numerical analysis of conical indentations simulated with the finite element method [...].

Keywords: elastic deformation; finite element method; nanoindentaion; numerical analysis.
