DEVICE FOR MEASURING lateral deformation of cylindrical samples under axial LOADING

摘要

The invention relates to the field of measuring technique, particularly for testing construction materials of samples under laboratory conditions and aims to reduce the complexity of the measurement of transverse strain cylindrical samples under axial loading, improving the accuracy of measurements and obtaining more complete information about the sample deformability. Said technical result is achieved in that the device for measuring the transverse deformations of cylindrical samples under axial loading, comprising a frame for mounting the measuring dial gauges and contact strips for fastening the device to the test cylindrical sample frame is in the shape of a polygon, e.g., correct, openings measuring fastening of indicators arranged in a plane passing through the center of gravity of the cross section of the frame, and their axes pass through geometrizes matic center frame and define between them equal angles, contact strips placed inside the frame, edges of strips perpendicular to the plane rigidly fixed studs placed movably in the holes in the faces of frames, the axes of which are symmetric axes of the mounting holes measuring indicators.
