Other reasons attributed to larger calculated values of the elastic modulus can be the indentation pile-up, the indent size effect, and the elastic recovery [31].
For low indentation loads, cracking initiates only at the tips of the indent (primary cracking).
For small indentations a constant ratio between the maximum misorientation beneath the indent flanks and the diameter of the imprint was found.
However, many indentation studies have revealed only a few shear bands surrounding the indent on the top surface of the specimen.
It was shown that reduction of the indent size leads to both increasing hardness and decreasing plasticity, determined by indentation.
The projected area quantified by the radius (d) of interacting volume underneath the indent tip can be a better representation of the affecting area by indentation.
The analysis based on a simple model indicates that Ac is always smaller than Ar, and the more heavily the indent piles up (or sinks in), the larger the difference between the nano-indentation hardness and microhardness.
In Tiffany's bedroom a stained pillow bore the indent from her head.
Place the stuffing into the indent, seal carefully and gently roll into a ball.
And a bead of desperation formed in the indent above the center of her lips.
Sure, the walks are lovely, but you could easily miss a detail such as the indent in the rock at the top of Dunadd Fort where kings would place a foot during their coronation ceremony.
