Experimental Verification of Conjugated Strength Criterion

František Fojtík, Martin Fusek


The paper describes the experimental results for the fatigue loading of the specimen manufactured from the construction steel 11523. The first set of the specimen was loaded by the alternating torque amplitude. The second set was loaded by the alternating amplitude of the bending moment and the third set of specimen was loaded by the alternating amplitude of the tensile/pressure. The conjugated strength criterion was applied on the experimental results. The required input parameters for the conjugated strength criterion were obtained from the stress-strain analysis of the specimen by the finite element method in the software ANSYS
