Determining the Contact Stiffness and Contact Area

and

, it is clear that in order to calculate the

hardness and elastic modulus from indentation load-displacement data,
one must have an accurate measurement of the elastic contact stiffness
(

S

) and the projected contact area under load (

A

).

One of the primary distinctions between IIT and traditional hardness
testing is the manner in which the contact area is derived. Rather than by
imaging, the area is established from an analysis of the indentation
load-displacement data.

The Power-Law Relation

The most widely used method for calculating the contact area was
developed by Oliver and Pharr. The Oliver-Pharr data-analysis
procedure begins by fitting the load-displacement data acquired during
unload to the power-law relation:

(8)

P

is the load applied to the test surface,

h

is the resulting penetration,

B

and

m

are empirically determined fitting parameters, and h

f

is the final

displacement after complete unloading (also determined by curve
fitting). The

contact stiffness

,

S

, is then established by analytically

differentiating

and evaluating at the maximum depth of

penetration, h = h

max

, or

(9)

Experience has shown that

does not always provide an

adequate description of the entire unloading curve, especially for films
on substrates. It is thus prudent practice to determine the contact
stiffness by fitting only the upper portion of the unloading data; fitting
the upper 25 % to 50 % of the data is usually sufficient.
