Large deformations generated by the purely angular shear

In order to overcome some formal ambiguities and the difficulties encountered in the application of classical shear models in experimental tests, the authors have recently proposed a new methodology to the problem that naturally extends the pure shear paradigm of linearized elasticity to the finite elasticity. In this paper, the governing equations of the purely angular shear are transformed so that they can be applied directly in experimental investigations, and numerical and experimental analyses are then developed. In particular, for this last analysis, a specific testing machine, which foresees the monitoring of the test by a Digital Image Correlation (DIC) instrumentation, was designed and built. The results provided by the three different approaches are compared with each other, with the ultimate goal of making the shear behavior of a material that can experience large deformations more comprehensible.
