DEVICE TO STUDY DEFORMATION PROPERTIES OF FLAT FIBRE-CONTAINING MATERIALS Russian patent published in 1997 - IPC

FIELD: study of materials. SUBSTANCE: device to study deformation properties of flat fibre-containing materials has loading spindle 16, mechanism to lift and lower loading spindle 16, bell-crank 5 rocking on axle of synchro transmitter 9, rod 13 hinged to bell-crank 5. Loading spindle 16 is provided with thin-wall ring 3 with strain-gauge transducers 4 enabling total stress and its relaxation emerging on various cycles of deformation of material to be measured and with mobile clamps 22, 23, 24, 25 arranged crosswise and holding sample 15 in plane perpendicular to action of loading spindle fitted with strain-gauge transducers 26, 27 which allow stresses emerging in mutually perpendicular direction with deformation of sample 15 to be recorded. EFFECT: expanded application field, improved authenticity of studies. 3 dwg
