Accordig to the source (VTK/Graphics/vtkExtractTensorComponents.cxx)
if ( this->ScalarMode == VTK_EXTRACT_EFFECTIVE_STRESS )
{
sx = tensor[0];
sy = tensor[4];
sz = tensor[8];
txy = tensor[3];
tyz = tensor[7];
txz = tensor[6];
s = sqrt (0.16666667 * ((sx-sy)*(sx-sy) + (sy-sz)*(sy-sz) +
(sz-sx)*(sz-sx) +
6.0*(txy*txy + tyz*tyz + txz*txz)));
}
I think that this should correspond to the Von Mises effective stress.
Does it?
