  • A comparative study of the probabilistic fracture mechanics and the stochastic Markovian process approaches for structural reliability assessment


The two computer codes COVASTOL and RELIEF, developed for the modelling of cumulative damage processes in the framework of probabilistic structural reliability, are compared. They are based respectively on the randomisation of a differential crack growth law and on the theory of discrete Markov processes. The codes are applied for fatigue crack growth predictions using two sets of data of crack propagation curves from specimens. The results are analysed critically and an extensive discussion follows on the merits and limitations of each code. Their transferability for the reliability assessment of real structures is investigated.
