One-dimensional elongation of a cubic crystal
Z. WESOLOWSKI
 
Large elongation in one de?nite direction of a crystal of cubic symmetry is considered. The equations of second order elasticity theory are applied. In this approximation three constants of the second order and six constants of the third order characterize the crystal. The stress is a function of the elongation direction. The elongation directions for which the stress reaches an extreme value have been analyzed.
 
Keywords:
cubic crystal, elongation, material nonlinearity.
