Abstract

An improvement in the method of fatigue testing of rubber specimens in the form of dumbbells (GOST 10952-75. Rubber. Methods for determination of fatigue life under variable sign flexure with rotation) is proposed. The temperature of self-heating of each test specimen proposed to associate with the true deformation of this specimen. The resulting dependence is used for a more rigorous construction of the Weller fatigue curve: not the average values of the number of cycles to failure of all tested samples Nav, but the number of cycles to failure Ni of each tested sample are plotted. The advantage of the proposed technique is also the rejection of the need to compliance the proximity of temperatures of all tested samples according requirements of GOST. The developed technique is recommended to be applied when processing the results of fatigue tests by the method of alternating bending with rotation for different rubbers.
