Ja. Bea et al., Evaluation of the probability distribution of crack propagation life in metal fatigue by means of probabilistic finite element method and B-models, ENG FRACT M, 63(6), 1999, pp. 675-711
In this paper, a new model for the prediction of the cumulative distributio
n function of fatigue life of structural elements during the crack propagat
ion stage is established. This problem is considered as a cumulative damage
process following the probabilistic approach of Bogdanoff and Kozin (B-mod
els). The initial and final crack lengths, the crack propagation angle, the
material fracture and elastic parameters and the external loads have been
the random Variables considered here. The theoretical bases of the model an
d the procedure to construct it are described in the forthcoming paragraphs
such as several examples for mode I problems including the comparison with
experimental results. (C) 1999 Elsevier Science Ltd. All rights reserved.
