Paper Abstract

According to the anisotropic elasticity theory, the contraction ratios along [110] take negative values for a number of metals when the single crystals are subjected to uniaxial forces along [110]. The pure bending tests employing holographic interferometry were conducted to confirm this phenomena using copper single crystals. In this study , the expression describing the morphology of contour lines of the anisotropic materials subjected to pure bending was presented in terms of the elastic compliances. It was suggested from this expression that, as contour lines, the positive values of contraction ratio provide hyperbolas, on the contrary, the negative values provide ellipses. The experimental results were in good agreement with the results expected analytically.
