Ja. Goshawk et Rs. Jones, CONSTITUTIVE-EQUATIONS FOR ANISOTROPIC CONTINUA, Composites. Part A, Applied science and manufacturing, 29(1-2), 1998, pp. 133-140
Two classes of simple constitutive equations for continuous fibre-rein
forced composites are introduced. In the first, the transverse and lon
gitudinal viscosities are functions of invariants of the rate-of-strai
n tensor and the fibre-orientation vector. In the second, anisotropic
yield conditions are imposed. The response of each of the models in a
stratified flow is considered. (C) 1997 Elsevier Science Limited.
