Striation thickness reduction from geometrical arguments

1 Striation Thickness Reduction from Geometrical Arguments 

FIGURE 6.7 Layered structure and definition of striation thickness S. 

The area Ao is now subjected to strain with principal directions in the Cartesian coordinates and with principal elongation ratios kx,ky, and A, (Erwin, 1978a). The area Ao will become A, and the vectors defining A are a, b, and d, so that 

Our primary interest is in the calculation of the change of the interface Aq, and thus we form the ratio of the interface after mixing has started to the initial interface (at time t = 0), which is also called the mixing number frequently in the literature

As mixing progresses, the interfacial area per unit volume increases and the striation thickness decreases. If there is a distribution of striation thickness then not only the mean but also the variance should be taken into consideration for the quality of mixing calculations. In Section 6.3.1 the interfacial area growth, or equivalently the striation thickness reduction, is calculated from geometrical arguments.
