FIELD: physics.
SUBSTANCE: apparatus has a stand with two supports, a clamping support, a loading and a removable base plate, and a wedge with angle α in a wedge mechanism. One of the supports is in form of a wedge with one working surface and angle α/2, and the wedge angle α is determined by solving a system of equations.
EFFECT: high accuracy of compression testing a sample made from sheet material under linear stress conditions.
