Stiffness (N/m)
: Contact stiffness, averaged over all valid indents in the
test array. If the contact stiffness is more than 10 % of the frame
stiffness, best results may require the determination of frame stiffness
on the test sample using the
method.
Express Test to a Force
The purpose of the method is to use Express Test for rapid
characterization of Young's modulus and hardness by performing an
array of indentations to a user-defined force and is available as both
Batch (Method Name-Batch) and Individual Methods. The method may
be used on bulk materials or for the mapping of mechanical properties.

Adjust the Panel Inputs as needed:
•
Memo
: Provides space for user-specified information about each
test.
•
Poisson's Ratio
: The Poisson's Ratio for the test material.
•
Prescribed Load
: Maximum indentation force.
•
Surface Approach Distance
: This input may either be set to
Standard or High. Use the High setting for rough samples. Using
High will increase test time.
