Probabilistic sensitivity analysis of dwell-fatigue crack initiation life for a two-grain microstructural model

Crack initiation in Ti-6242 has been observed to occur in a grain with a hard orientation for basal slip neighbouring a grain with a soft orientation. Because there is significant variability in microstructural features and crack initiation life, it is useful to explore the effects of the variability of the microstructural components through a probabilistic sensitivity analysis. In this paper, ...

Probabilistic Fatigue Crack Growth Analysis of Offshore Structures, with Reliability Updating Through Inspection

A stochastic mtiel for fatiguecrackgrowth is applied.which accountsfor uncertainties in loading, initialand critical defectsizes,materialparameters includingspatialvariation,and in the uncertainty relatedto computationof the stressintensityfactor. Failu~ probabilities are computed by first-and second-orderreliability methods and sensitivity factorsare &termined. Model updating based on inservic...

Probabilistic Prognosis of Non-Planar Fatigue Crack Growth

Quantifying the uncertainty in model parameters for the purpose of damage prognosis can be accomplished utilizing Bayesian inference and damage diagnosis techniques such as non-destructive evaluation or structural health monitoring. The number of samples required to solve the Bayesian inverse problem through common sampling techniques (e.g., Markov chain Monte Carlo) renders high-fidelity finit...
