The anisotropy of aluminum and aluminum alloys

A Taylor/Bishop-Hill model describes the plastic anisotropy of aluminum single crystals under constrained deformation. The anisotropy of textured aluminum is approximated quite well by a yield criterion with an exponent of eight. The use of this criterion in analyses of metal forming has led to better understanding of the formability of aluminum and other metals. The effect of anisotropy on the limiting drawing ratio (LDR) in cupping is less than would be expected from the quadratic [R.
