compute Taylor factor and strain dependent orientation gradient
Syntax
[M,b,W] = calcTaylor(eps,sS)Input
| L | velocityGradientTensor |
| sS | slipSystem |
Output
| M | taylor factor |
| b | coefficients for the acive slip systems |
| W | spinTensor |
Example
consider uniaxial tension in (100) direction about 30 percent
F = deformationGradientTensor.uniaxial(vector3d.X,1.3)F = deformationGradientTensor (y↓→x)
rank: 2 (3 x 3)

0 0.8771 0
0 0 0.8771the corresponding rate of deformation tensor becomes
L = logm(F)L = velocityGradientTensor (y↓→x)
