On the state of pure shear

Jovo P. Jarić, Dragoslav S. Kuzmanović, Zoran Đ. Golubović

The algebraic proof of the fundamental theorem concerning pure shear, by making use only of the notion of orthogonal projector, is presented. It has been shown that the state of pure shear is the same for all singular symmetric traceless tensors in E_3, up to the rotation.
