MACHINE TO TEST MATERIALS FOR CREEPING AND DURABLE STRENGTH (VERSIONS) Russian patent published in 2014 - IPC G01N3/08 

Abstract RU 2529780 C2

FIELD: testing equipment.

SUBSTANCE: invention relates to testing equipment, in particular, to machines for mechanical tests by stretching, for instance, geosynthetic materials for road surfaces, etc.. and may be used in appropriate fields of engineering. A machine comprises grips for samples, comprising upper and lower clamps, a lever-jockey weight device connected to the upper grip, drives of the jockey weight and the lower grip connected to a control block. grips of samples are arranged in series, at the same time movable clamps of grips are balanced with counterweights, and upper and lower clamps in each grip have limitation of travel relative to each other. The second version of the machine differs from the first one by the fact that between the lever-jockey weight system and grips there is additionally installed a force-measurement sensor.

EFFECT: provision of simultaneous testing of several samples and possibility to install random number of samples from one to the number of grips installed in a machine, and also smooth and quick application of load to samples.
