The response of anisotropic materials under homogeneous large plastic deformations has been extensively studied in recent works which employ the concept of plastic spin in order to determine the evolution of the anisotropic orientation. The present work extends the investigation to non-homogeneous large plastic deformations for materials with orthotropic and transversely isotropic symmetries. The inhomogeneity of deformation is characterized by the development of different kinds of folds. Closed-form analytical solutions are obtained which provide a clear insight into the effect that the intensity of anisotropy and the plastic spin have on the formation of such folds. The analysis is illustrated by examples. © 1992 Pergamon Press plc. (EN)
