• Though there are many questions in plasticity, we think, one of the most important subjects is to make clear the relations among pure shear, simple shear, tension and compression, But the relation between pure shear and simple shear is solved not only by theoretical considerations but also by experiments. In this paper, we examined the relations among pure shear, tension and compression in plastic domain with the material that was considered to be isotropic in the virgin state, and obtained the correct experimental relations. The experimental relations are shown in Fig. 5. In this figure, the shearing stress is taken in ordinate and the strain corresponding to the amounts of total slip is taken in abscissa. These results show evidently that the relation between tension and compression coincides well and pure shear is higher about 14% than tension or compression in all plastic domains.
