METHOD OF ACCELERATED MATERIAL FATIGUE TEST Russian patent published in 1995 - IPC

FIELD: accelerated testing of parts of machines. SUBSTANCE: program units have several different stages of loading; voltage amplitudes are constant at any stage. At the beginning of the loading, the stages with pressure amplitudes are eliminated which are less than value of FATIGUE limit of the part or material. Then, as number of cycles of loading increases, the stages are introduced into program units which have amplitudes less than FATIGUE limit. In this case, the stages are introduced in sequence of amplitudes decrease. EFFECT: simplified process of testing. 1 dwg
