In our previous study, using the method of image analysis based on the Natural Strain theory, the distributions for shear strain in the cross-section have been investigated when a large torsion is applied in the lubber test specimens. As a result, it has been revealed that there is difference between the experimental results based on Saint Venant’s torsion theory and the results based on present image analysis. Moreover, it became clear that the results based on modified Saint Venant’s torsion theory for the gauge length of test specimens approach to the results based on the present image analysis. However, it has not been examined the distribution of shear strain for specimens that have rectangular cross-section other than square cross-section. Therefore, the distribution of shear strain in the rectangular cross-section is compared with the distribution of shear strain in the square cross-section in this study. As consequence, the effect of elongation in the narrow side more increase as compare with wide side.
