Taylor factor from orientation gradient

Syntax

[M,b,eps] = calcInvTaylor(mori,sS)

Input

mori misorientation
sS slipSystem list in crystal coordinates

Output

M taylor factor
b coefficients for the acive slip systems
eps strain tensor list in crystal coordinates

Example

% define 10 percent strain
eps = 0.1 * strainTensor(diag([1 -0.75 -0.25]))
eps = strainTensor (xyz)
  type: Lagrange 
  rank: 2 (3 x 3)

% define a crystal orientation
cs = crystalSymmetry('cubic')
ori = orientation.byEuler(0,30*degree,15*degree,cs)
