SCLEROMETER Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed invention makes it possible to increase accuracy of calculation of indices of mechanical properties of investigated materials thanks to making scratch of constant cross-section in investigates flat sample and thanks to possibility of determination of total force of scratching. Sclerometer used for these purposes has case 1 with baseplate 2, table 4 for attachment of samples 5, pendulum with indentor 7 on its end, stopping unit composed of device to measure deviation angle of pendulum and strain-measuring meters. Indentor is joined to pendulum and is spring-loaded along its axis. Strain-measuring meters. Indentor is joined to pendulum and is spring-loaded along its axis. Strain-measuring meters are installed between table 4 for attachment of samples and baseplate 2. EFFECT: increased accuracy of calculation of mechanical properties of investigated materials. 2 dwg
