Abstract
Carbon fiber reinforced plastic (CFRP) possess high-specific strength and is applied to various member of structure. It has been clarified that delamination and deformation of fiber occurred on CFRP, a fiber composite and laminated material, from repeatedly applying of loads. However, strain distribution behavior that takes account of stress concentration zone such as groove and circular hole has not been clarified yet. In this research, we conduct cyclic load examination of torsional moment using digital image correlation method, and the residual strain distribution behavior of circular hole's surrounding of CFRP with circular hole was observed. As a result, we have clarified that the behavior of residual strain distribution relies on fiber orientation. Moreover, we also have clarified that the size of residual strain is affected by fiber orientation, with respect to the number of cycles of repeated load torsional moment.
