Abstract
A device for gripping a specimen for applying to the same tensile or torsional strain includes two plates spaced from each other and a tubular spacer extended between the two plates and accommodating a specimen. The specimen is attached to the plates by respective nuts. One end of the specimen extended outwardly from the respective plate and nut is formed by a threaded pin, on which a pulling device for applying tensile stress onto the specimen, is set. The other end of the specimen has a square portion to which a tap wrench is applied, which, with the aid of two bolts positioned on one of the plates, applies torsional strains to the specimen.
