Although deformation takes place within the entire area between the frosted grips, the moderately to highly strained regions concentrate along the lower SZB during the first part of the experiment. At higher shear strain, however, the trace of the intermediate to high strain zones tends to connect with the upper left corner of the analogue sample showing a diagonal arrangement.

In contrast, the highest strained parts (orange to red contour intervals) of the sample show always an enechelon-like oblique orientation with respect to the SZB.
