METHOD FOR COMPARATIVE EVALUATION OF MATERIALS BASED ON RATIO OF TOTAL LENGTH OF PENDULUM SCRIBING TRACE TO LENGTH OF REBOUND DIMPLE

摘要

FIELD: physics.SUBSTANCE: method comprises one-time loading of material with indentation by pendulum scribing; measuring the scribing results; establishing a relationship between the measurement results and investigated physical-mechanical properties of materials and predicting operational properties of the compared materials; implementing a pendulum scribing mode, where an indenter at the beginning of interaction with a sample forms a rebound dimple on the surface of said sample; measuring the total length of the scribing trace and length of the dimple; determining the ratio of the total length of the trace to the length of the dimple and judging physical-mechanical and operational properties of the material based on the value of the ratio.EFFECT: simple method of evaluating physical-mechanical properties of material with pendulum indentation, predicting efficiency of using compared materials in identical operating conditions by enabling ranking thereof according to the value of a parameter measured during inspection.2 dwg, 2 tbl
