Sheet metal r-value determination with Models 3575
shown in the photo, a Model 3575 may be used simultaneously
with a Model 3542 axial extensometer to measure
r-value. Many researchers are now using only this
single lateral measurement for their tests, rather
than the older method using three manual measurements.
An alternate with dual lateral measurements is the
3575AVG model, which averages readings over two
