The Effect of Materials of One-Bar-Method Type Testing Machine on Dynamic Tensile Properties of Specimen

Abstract

With a one-bar-method type dynamic tensile testing machine, dynamic behavior of Al alloy thin plate specimen was affected by the materials of the testing machine. An initial peak was appeared frequently on the stress-strain curve. Varying with the testing machine materials, that is, steels and Al alloys, the most reliable behavior of the specimen was obtained by the machine of all Al alloys, for 7075-T6 Al alloy specimen of 1mm in thickness.
