Werner, I remember all the ads and hype surrounding the hydraulic tester as it was supposed to be the "end all" in ductility testing. Didn't the foil still have to be in clamps much as mechanical pull testing is done most of the time with a dogbone specimen? I've, and haven't we all, been using the dog bone tensile and elongation testing since something like 1965 despite some of its obvious drawbacks though averaging out a number of tests provides reasonably good data.
