The two-dimensional strain history on a sheet which is inclined to the principal axes of the strain ellipsoid is considered. Even if the strain history in three dimensions is coaxial, the two-dimensional progressive deformation on the surface of the sheet is in general of a non-coaxial type. It is shown in this paper that the degree and sense of two-dimensional non-coaxiality is governed by the strain path followed during three-dimensional coaxial deformation. The general relationship is defined between the gradient of the strain path on the Flinn strain ellipsoid diagram and the nature of the two-dimensional strain increments. For most strain paths an asymmetrical arrangement of structures in the oblique sheet is to be expected. Hence, en échelon folds, transected folds and extension veins with curved fibres could be produced during three-dimensional coaxial deformation. Only if the strain path is of a rather special type will the deformation be coaxial in a two-dimensional as well as a three-dimensional sense.
