The macroscopic elastic behavior of polycrystalline metal subjected to tension is examined by two dimensional FEM simulation. The grain is modelled by a regular hexagon in which elastic constants, such as modulus of elasticity, are constant and given as a function of the angle between load direction and crystal direction. In the FEM analysis, each grain is assumed to be homogeneous and isotropic. The macroscopic elastic constants are obtained from the conception of gauge lengths set up in longitudinal and lateral directions. From the results, we can specify the size of the polycrystalline metal, where the macrcoscopic elastic constants are not affected by microstructure (grain size) ; i. e., the metal can be considered as macroscopically continuous.
