H. Xiao, ON ANISOTROPIC SCALAR FUNCTIONS OF A SINGLE SYMMETRICAL TENSOR, Proceedings - Royal Society. Mathematical, physical and engineering sciences, 452(1950), 1996, pp. 1545-1561
Irreducible functional bases for anisotropic scalar functions of a sin
gle symmetric second-order tensor under all 32 crystal classes are pre
sented for the first time. For most cases, the presented results are m
ore compact and simpler than the well-known results for integrity base
s.
