METHOD OF PROXIMATE DETERMINATION OF STRENGTH CHARACTERISTICS OF SOLID MATERIALS Russian patent published in 2004 - IPC

FIELD: measurement technology; prompt estimation of physico- mechanical properties of solid materials. SUBSTANCE: proposed method includes penetration of indenter into material under test, determination of depth of remaining impression on surface of this material and estimation of its strength characteristics. To this end, preliminary load is applied at point under test perpendicularly to plane of material under test for obtaining check impression which is beginning of reading of measurement of depth of indenter penetration, after which main load is created at point under test and depth of indenter penetration is measured; then, indenter is kept under total load for 120- 150 s and depth of indenter penetration and total depth are measured during this period of time, after which load is removed and indenter left under preliminary load for 30-50 s and then this load is removed. EFFECT: enhanced reliability of measurements. 1 dwg
