| Abstract: | A major problem in strain analysis of ellipsoidal fabrics is how to separate the effects of initial preferred orientation of objects from the effects of strain. New algebraic methods are presented here which apply to many of the situations previously analysed by graphical and iterative techniques. The algebraic solutions are simple and highlight some assumptions implicit in previous methods, and the relations between those methods. It is shown that many final ellipsoidal fabrics cannot be produced from initial fabrics which were symmetric with respect to bedding, and that a three-dimensional analysis is preferable to analysis on two-dimensional section planes. |
