On the Electronic Recorder of Stress-Strain Curve

概要

In the static test of materials, to get more precisely and easily the relation between load and deformation, we designed a electronic recorder and tested. We made use of differential transformer for strain pick up and of slide wire for load pick-up. Load-recording and strain-recording elements are mutually independent and both have the null balance circuits. This electronic recorder is very helpful to get the stress-strain curves of materials such as steel near the yielding point and cast iron up to fracture.
