...It was also noticed that several studies reported FEA result of nanoindentation containing clearly perceivable noise (Antunes et al., 2007; Bolshakov and Pharr, 1998; Chen and Vlassak, 2001; Larsson et al., 1996)....

...The other source that was limiting our ability to quantify the change of mechanical properties was the inability of the widely used method (Oliver and Pharr, 1992) to estimate the contact area accurately when the material piles up around the indenter (Bolshakov, 1996; Bolshakov and Pharr, 1998; Cheng and Cheng, 1998, 2000)....

...For example Hay et al. (1999) have reported results of axisymmetric FEA of conical indentation by four different cones with half-included angles of 42.28º, 60º, 70.32º, and 80º. Noting that their mesh consisted of square elements 5nm on a side in the region of contact, the possible error in contact…...

...Comprehensive studies of various aspects of nanoindentation using FEA are available in the literature (Bolshakov, 1996; Hay et al., 1999; Shim, 2007)....
