An Analysis of Cyclic Deformation Based on Dislocation Dynamics in Copper

概要
- 論文の詳細を見る
A new approach was made for the cyclic deformation in terms of dislocation dynamics which is derived from modifying Johnston-Gilman's theory, and the change in the flow stress during cyclic deformation was analyzed in annealed copper. The analysis was quantitatively in fairly good agreement with test results as well as qualitatively. On the other hand, the Bauschinger effect could not be expressed well by the present analysis, and therefore, the stress-strain hysteresis loop estimated had a "fatter" shape than the actual one. This suggests that more detailed study will be needed for the evaluation of the internal stress produced by the reversed strain.
