review text: In this paper, a simple mechanical model of polycrystal is suggested on the basis of the crystal plasticity. This model incorporates interactions among grains in polycrystal and interactions among slip systems in a crystal grain component. Especially, an equation for a slip strain of slip system is based on a theory of thermo-activation motion of dislocation. In this way, the model can take into account rate (creep) properties and temperature effects as well as an induced plastic anisotropy depending on deformation path, under multi-axial condition. Some computations are done by using the model for typical sets of strain paths and compared with corresponding experimental results of aluminium alloy at \(200^ oC\). The computational results reproduce accurately typical features observed in the experiments.
