For the purpose of measuring large-true strains up to 50％ or more, two new-type strain-measuring devices were fabricated and tested.One was applied to measure large tensil and compressive strain and the other to measure latge torsional shearing strain.Both devices are able to measure true (natural or logarithmic) large strains mechanically and convert them into usable electric signals, which are recorded on a pen-recorder.It is found from the test results that the new-type strain-measuring devices are able to measure large true strains up to several tens of percent stably and precisely similarly to electric wire resistance strain gages.
