FIELD: test engineering.
SUBSTANCE: invention refers to facilities for determining physic-mechanical properties of materials and can be implemented as process equipment in aircraft engineering, ship building and other branches of machine building. The facility consists of a loading claw and of a supporting element forming movable kinematic pair with a case, whereto two brackets are secured on both sides, each of them containing an internal cavity. A movable and fixed rack bars are arranged in this internal cavity, thus forming gearing with a gear installed in the bracket. A stop for contact with installed levers of the fixed element is attached to the axle of gear. All movable parts are kinematically interacted.
EFFECT: facilitating compression of billet l≤(3…4)·d to relative deformation ε=2h/l per one set, also l is length of billet, d is diametre of billet, h is length of end portions of billet projecting from supporting element before beginning of compression.
