“…This indicates that only a part of amorphous phase is highly oriented. This scattering should be the same as that observed for PET film by Mahendrasingam et al 20,[22][23][24] and Kawakami et al 31,32 Crystal diffraction appeared abruptly 20 ms after necking. It is not observed at all in the 17 ms diffraction image, and becomes clear in the 30 ms image.…”

“…In addition, the fiber structure development process is not analyzed by the latter category of studies. The results reported by Mahendrasingam et al [21][22][23][24][25] are notable, because they reported x-ray diffraction images for the highest strain rate. They observed orientation-induced crystallization behavior by the images that were measured every 40 ms for a batch drawing process at strain rates of 0.01 to 15 s -1 , temperatures of 90 to 120°C, and draw ratios of 2.2 to 4.0.…”

“…This effect is related with the strain induced modification of the microstructure of PET [3,4,5]. The model (Eq.1) has been identified supposing the strain and stress fields uniformity in the PET specimen.…”

“…The material characterisation technique using the biaxial stretching machine was not able to replicate the sequential deformation type for every foreseeable stretch scenario; indeed, only constant width and pure biaxial deformation were captured. The amount of initial linear stretch, and therefore the onset of orientation and eventual strain hardening [19][20][21][22][23][24][25][26][27][28][29], significantly affects the inflation of the preform.…”
