FIELD: physics.
SUBSTANCE: article is loaded in cycles from zero with gradually increasing amplitude until the onset of acoustic emission signals before the end of unloading; maximum loads of the cycles are recorded and the maximum nondestructive load of the article is determined, wherein loading is carried out with constant rate of deformation equal to the rate of deformation of the article in operating conditions; spontaneous reduction of the maximum load when loading is stopped is recorded; total deformation of the article under maximum load and residual deformation after unloading is measured and the value of total creep for a load which is equal to or less than the maximum nondestructive load is determined.
EFFECT: possibility of estimating resistance of an article during loading with simultaneous determination of the maximum nondestructive load and total creep.
