METHOD OF DETERMINATION OF FATIGUE RANGE OF METAL MATERIALS Russian patent published in 1997 - IPC

Abstract RU 2082146 C1

FIELD: testing technology, strength testing, evaluation of quality of metal materials. SUBSTANCE: tested sample is loaded statically, stress (σк) of transition from linear accumulation of residual deformation to nonlinear one with subsequent loading of another sample identical to first one with lesser stress is determined. Then value of linear relaxation is measured. After this fatigue range is evaluated by measured parameters of static loading and stress relaxation. EFFECT: increased authenticity of method. 2 cl, 2 dwg, 1 tbl
