Corrections to B-models for fatigue life prediction of metals during crack propagation

Abstract: SUMMARYIn this paper a new model for the prediction of the Cumulative Distribution Function (CDF) of fatigue life of structural elements during the crack propagation stage is described. This problem is considered as a cumulative damage process following the probabilistic approach of Bogdano! and Kozin [1] (B-models). The initial and "nal crack lengths, the crack propagation angle, the material fracture and elastic parameters and the external loads may be considered as random variables. In this initial approach… Show more

“…Second, the strain values of three directions (0°, 45°, and 90°) could be collected by a dynamic data collector. The maximum and minimal strain values were calculated by equation (6) where e max is the maximum strain value; e min is the minimal strain value; e 0 , e 45 , and e 90 are the strain value along the direction of 0°, 45°, and 90°, respectively.…”

“…In 1920, Griffith 5 developed a theoretical and experimental research of glass brittle fractures and proposed an energy theory of crack propagation, which is the foundation for fracture mechanics. Bea et al 6 proposed a new model of predicting the fatigue crack propagation life of metal structural components. In this new model, they measured the initial and final crack lengths, crack propagation angle, fracture parameters, elastic parameters, and external load as random variables.…”
