Abstract

Provided is a fixture applied to sticking a strain gauge on a Hopkinson square bar and a use method of the fixture. The invention is specially designed for a square waveguide bar, and the fixture further ensures consistency of the same group of strain gauges along a cross-section position of the bar. The fixture has important practical value in application in a dynamic true triaxial electromagnetic Hopkinson bar test, especially in a high-end material testing field requiring high-precision and high-reliability test data.
