The AverEdge32™ option, available for the AVE2, is an advanced capability available in
Bluehill
®
Universal software for measuring strain using the edges of the specimen
instead of dots placed on the specimen. It requires a different mounting system that
includes a back screen.
Transverse strain is measured at multiple locations along the specimen’s edges and
averaged to provide a smoother, more repeatable measurement.
It is particularly useful for determinations of the plastic strain ratio (r-value) on
specimens that exhibit localized plastic deformation (Luder bands).
