During progressive simple shear deformation, linear elements rotate so that there is a tendency of all the linear elements to align themselves parallel to the direction of the bulk shear. The amount of rotation may thus be considered as a fundamental measure of the degree or intensity of shearing, i.e. by how much the shearing has progressed or advanced. This (i.e. the degree or intensity of shear deformation) has been expressed here by identifying two parameters rotation angle (θ) and coefficient of rotation (ω) that give an idea of the degree or intensity of shear deformation at two or more points of a shear zone, especially in a comparative way.
