METHOD OF TESTING STRUCTURAL MATERIAL FOR FATIGUE STRENGTH UNDER ACCIDENTAL CYCLIC LOADING

摘要

This invention relates to mechanical testing m relates to methods for fatigue testing at random loads. The object of the invention - method of improving the accuracy and strength result in loading at higher frequencies. Determined load and temperature in the operating conditions and eliminate the load from below the level of damage to loops. When loading this load sample further loaded harmonic load below the level of damage until the temperature of the sample corresponding to the operational value. yl 3
