Data Comparisons
Experimental Validation
AS4/PEEK: Fractal parameters were calculated from profilometric measurements. Model results are compared with experimental data of Lee and Springer (1987)
Experimental Correlations
Fractal parameters determined so as to fit reported data [Dara and Loos (1985); Lee and Springer (1987); Butler, et ai. (1998)]
- Method I: Estimating one set of fractal geometric parameters for each of the 3 investigations.
Assumption: the materials are nominally the same from one experiment to another.
- Method II: Material variations from one experiment to another are accounted for, and the fractal geometric parameters were determined for each experimental set.
