Description

Texture (preferred orientation) has a significant influence on the formability of metals. This was shown experimentally for rolled steel sheet by Stickels and Mould [1]. They found a correlation between the in-plane angular variation of r-value and the anisotropy of Young’s modulus, E, as measured by ultrasonics. The r-value is a measure of plastic strain on deep drawing, defined as ϵyy/(∈yy + ∈zz), with ∈yy the in-plane strain and ∈zz the strain in the thickness direction.
