During the experiment a dextral shear sense was imposed on the sample and soon after deformation started, needle shaped paraffin-grains developed a preferred grain shaped orientation (s₁) (Figure 7 or Movie 2 ). The preferred grain shape orientation relative to the shear zone boundary was not constant. On the left side of movie 2 the grain shape fabric was inclined at a constant angle, while on the right hand side the grains built a concave structure in the annular shear zone. This indicates that deformation on the left hand side includes a shortening component perpendicularly to the shear zone boundary. Along the inner grip strongly elongated grains are common, oriented oblique to the shear zone boundary. Finite strain was not homogeneously distributed over the sample and increased towards the inner grip. Locally, along the outer grip in a domain (H) with elongated grains, a fabric change is visible (Movie 2) with an indication of dextral shear sense. This domain of higher strain gradually widens during the experiment. A hole on left side of the sample closed during the experiment.(Figure 8)
