Evaluation of microscopic deformation behavior of polycrystalline metals is very important to predict the mechanical property of the material. In this study, a development of the microscopic deformation field of polycrystalline pure copper is evaluated by digital image correlation method. Then, slip deformation on each slip system is estimated from the in-plane components of strain tensor based on the concept of the crystalline plasticity theory. Experimental results clarified that microscopic nonuniform deformation in the crystalline grain were evaluated, and that slip deformation occurred on specific slip systems.
