GS25 Fundamental Study on Finke Strain Measurements using Image Analysis : Strain measurements of Simple Shear under different deformation path and Development of Local Deformation
Details
This paper describes the method of finite strain measurement based on image analysis. The effectiveness of this measurement method based on the Naomi Strain Theory has been verified by comparing the strain measurement by the image analysis with the conventional measurement based on the displacement meter. The behaviors of the local deformation under uni-axial tension have been investigated in on previous study. However, the detail studies on the local defamation for simple shear have not been examined yet. So, in this study, the simple shear, which is gemmed under different deformation path, are discussed. Especially, developments of local deformation generated under different types of deformation history, which are obtained by applying the simple shear to the reversed direction alter the forward direction, are examined.
