Here *s/b* is the distance from the first node of the segment, , at which the segment’s strain is reported and *b* is the width of the segment. The strains are:

is the axial strain in microstrain, that is times the nondimensional strain.

is the curvature in microstrain/mm.

is the shear strain in microstrain.

is the twisting curvature in microstrain/mm.
