FIELD: testing equipment.
SUBSTANCE: invention relates to the field of "Physics of the material contact interaction" of hard flat body with a porous material environment, and is intended to determine its parameters of deformability and strength. Essence: the material environment is loaded with rigid flat perforated stamp with stepwise increasing load until the moment of loss of bearing capacity of the environment and sustainability of the stamp on it. The parameters of pressure pi and deformation Si of the environment at loading are controlled in time and a graph of test is plotted, by which the parameters of strength and deformability of the environment are determined. Each stage of deformation of the environment is kept constant in time to its conditional stabilization. Before setting the next steps of the deformation of the environment the elastic load cell is fixed with a locking screw of the load device. The device consists of a housing with a working chamber, fixedly mounted on the bottom of the chamber of the lower rigid flat perforated stamp, the working ring with a sample of the material environment, installed in the upper part of the working ring on the sample of the environment of the upper rigid flat movable perforated stamp and the loading device. The loading device consists of a rigid frame with an upper and lower beams and two guide racks, a pusher and a resilient load cell.
EFFECT: increased productivity of test of the environment on compressibility and strength.
