709 Alignment System Specimen Offsets 85
To see the bending due to the straightening of the specimen, the gauge offset can
be subtracted from the bent mean offset (bent mean relative to the gauge offset).
To see the bending due to the misalignment of the load unit, the bent mean offset
can be subtracted from the bent front offset (bent front relative to the bent mean).
The bending has X and Y components for each:
Xs – specimen bending strain in the x-axis
Ys – specimen bending strain in the y-axis
Xm – load unit bending strain in the x-axis
Ym – load unit bending strain in the y-axis
The following figure (Bending Components) shows the specimen bending and
load unit bending components for the middle gauges.
