Calculating Schmid factor for a certain grain?

[MTEXNewbie]

Let's say, I want to know the Schmid factor of the 3rd grain in the x-direction.

sigma = stressTensor.uniaxial(xvector);

% compute Schmid factor for all slip systems in the specific grain

SF = sS.SchmidFactor(inv(grains(3).meanOrientation) * sigma);

% find the maximum Schmidt factor

[SFmax,active] = max(SF);

SFmax

Is this approach accurate? Please suggest any smart way to do this.

I would really appreciate if the above method is the correct way to Calculate Schmid factor for a certain grain?

Hi,
if you meant to calculate the Schmidfactor with respect to a uniaxial stress parallel to the x-Axis, the answer is yes.

Yes it's parallel to x-axis, thanks for confirming.
