摘要：

Uniaxial compression experiments on copper single crystals, oriented to maximize the shear for one slip system, show activity on the primary slip system as well as appreciable activity orthogonal to the primary system. Utilizing three-dimensional digital image correlation, the amount of orthogonal slip has been quantified. The activity orthogonal to the primary occurs from the onset of deformation and varies from being equal to the primary for the as-fabricated samples to 115 of the primary in the samples annealed after fabrication.
