Abstract:

The plastic flow and fracturing properties of smooth sheet tensile specimens were determined by utilizing special instrumentation which has previously been developed to measure instantaneous values of the width, thickness and load. From these measurements the basic plastic flow characteristics in the form of true stressstrain curves were calculated. In addition to this, information on strain hardening and mechanical anisotropy was also determined. Due to the limited ductility of these specimens, some difficulty was encountered, particularly with the B120VCA Titanium Alloy. Also, because of the limited number of specimens tested and the inherent difficulties associated with low ductilities in this type of testing, it appears wise to consider these test results as tentative. The test specimens were H-11 or Vascojet 1000, B120VCA and 301 stainless steel cold rolled 70.
