Quantifying High-Performance Material Microstructure Using Nanomechanical Tools with Visual and Frequency Analysis

Figure 5

(a) The vertical long period of the SK76 UHMWPE fiber scan in Figure 3(a) established by both visual counting and frequency analysis using the Welch power density spectra method with example spectra seen in (b) and (c) where the tallest peaks indicate the vertical long period frequency.
