Compression Reports
Compression reports allow you to have your data overlaid with model data. You can choose the
optimize options for the equation to have the model data more closely fit the analysis data.
Modified Heckel Report
The original Heckel equation was developed and applied on ceramic and metal materials and,
later, modified for compaction of powders where the porosity is substituted for concentration and
pressure substituted for time.
Model
Displays equation parameters for the modified Heckel model.
Options
Applied
: reports the force applied from the upper piston only.
Mean
: reports the geometric mean of the force applied from the
upper and lower pistons.
Pressure range
: the pressure range on which the model is
overlaid; defaults to entire range.
Optimize
[equation parameter]: when selected, the software
recalculates model parameters in order to best fit the model with
the data.
