A procedure to handle the constitutive properties of materials with crystalline structure in computer simulation is examined, so as to treat mechanical interaction between the macroscopic field and the evolution of microstructures which constitute the elemental mechanism of plastic deformation. In this report, numerical analysis of opening of a central crack in a plane strain block is performed by means of a physical model of plasticity, whose properties are described on the basis of the crystal slip theory proposed by Asaro, et al. and it is shown that this model gives plenty of valuable information in microscale field and it has right to take the place of the phenomenologically formulated constitutive equation in computational plasticity.
