WebFrom the components of the stress tensor, we can calculate the pressureP= (xx+yy)=2, the normal stress differenceN= (yy xx)=2, and the shear stressxy. We define the normalized stress anisotropy to be˝^ = √ ^2 N+^2 xy, where ^N= N=P and ^ xy=xy=P.˝^ includes contributions from both the shear stress and the normal stress difference. WebIt is illustrative to consider the following example of a spherical tensors T(k) q (V~ ) = Y m=q l=k (V~ ) (1.11) 1Without resorting to a precise mathematical definition, this means that when we act with the rotation group on these tensors, for a given rank n, we get some big n2 × n2-dimensional rotation matrix.
