LOADER TO TEST MATERIALS FOR CREEP UNDER TENSION TOGETHER WITH TWISTING Russian patent published in 2000 - IPC

FIELD: mechanical tests of materials with combined loading to study effect of deformation on properties of materials under various temperatures. SUBSTANCE: this approach provides for expanded functional capabilities of loading of material of tested specimen from simple stressed state to complex loading. Holders of tested specimen are anchored on bed frame. Disc which axis matches axis of holders is made fast to one of holders. Two rollers with rotation axles are put on strip for rotation so that their rotation axes coincide with proper axes in strip. Loading unit is linked by flexible ties to disc via rollers. Loading unit is fitted with screw mechanism in the form of nut put on lower rod. Upper butt of rod has four lugs to accommodate axles of rollers. Loader also includes transducers measuring linear translations of rods. EFFECT: expanded functional capabilities of loader. 5 dwg
