Experimental Relations among Pure Shear, Tension and Compression in Plastic Domain

Abstract

In order to obtain the correct data in plastic domain under various kinds of loads, it is necessary that the material is isotropic in the virgin state. In this paper, the author examined the relations among pure shear, tension and compression in plastic domain with a kind of brass that was considered to be isotropic in the virgin state. The experimental results are shown in Fig. 4. In this figure, the stresses are taken in the ordinate and the strains correspond to the amounts of total slip are taken in the abscissa. This results evidently show that the relation between tension and compression coincide well and pure shear is higher by about 14% than tension or compression in all plastic domains.
