General Nanostructure Evolution in Load-Cycling Tests

3 General Nanostructure Evolution in Load-Cycling Tests 

During the mechanical tests SAXS patterns have been recorded continuously. Qualitatively these patterns are very similar, as is demonstrated in Fig. 6.4. Hence, it is necessary to extract structural parameters from the patterns with high precision and to analyze their variations. Inspection of the shape-evolution of the CDF peaks shows affine deformation, in contrast to TPU materials (cf. Chap.4). Thus the introduced simple nanoscopic structure parameters discussed here are considered to correctly describe the average response of the nanostructure to the applied macroscopic strain. 

The evolution of macroscopic-mechanical and of nanoscopic parameters during load-cycling tests is presented in Figs. 6.5, 6.6,6.7, and 6.8.
