抄録

3-Dimensional Optical Coherence Straingraphy (3D-OCSA) has been developed as a 3-dimensionally tomographic and non-destractive visualizing technique of micro strain distribution. This method can execute the 3-dimensional speckle deformation analysis based on recursive FFT-based cross-correlation technique of synthetic images, which are captured before and after loading by Optical Coherence Tomography. In this study, applying 3D-OCSA to Polymer Matrix Composites, the experimental feasibility study was carried out to evaluate micro-mechanics. Compared with simulated results obtained by image-based FEM, tomographic strain distribution had qualitative agreement with the simulated one, regarding the local strain concentration in the vicinity of fiber-bundle intersection. Therefore, OCS was verified to provide mechanical properties non-destructively as internal 3-dimensional strain distribution at the micro scale resolution.
