• Some typical and common features of history effects on plastic behaviours of polycrystalline metal observed in systematic experiments are analyzed from a view point of crystal plasticity. The single crystal component is selected as one of a face-centered cubic type. A simple mechanical model of polycrystal proposed in this paper reproduces qualitatively well the experimental results. This fact suggests that complex history effects observed in macroscopic experiments can be understood maily by a combination of some simple and fundamental deformation mechanisms of single crystal components. In this paper, a special postulate of isotropy proposed by Ilyushin is also confirmed to be valid with a reasonable accuracy by using the mechanical model of polycrystal.
