The compliances of an anisotropic polymer are calculated in terms of two mechanical modes of deformation. The first is a crystallite shear mode with displacement along the c-axis and is important in cold-drawn polymers which have a fibrillar structure with no discrete sub-structure within the fibrils. The second is interlamellar shear which involves slip between the crystal lamellae, which are oblique to the axis of chain alignment. It is the predominant mode of deformation an anisotropic polymers which have been heat-set subsequent to being cold-drawn.
