Using a sampling-based approach (either sequential importance sampling explicit Monte Carlo), this package can be used to perform a probabilistic damage tolerance for aircraft structures. It can model a single crack, or two simultaneously growing fatigue cracks (the so-called continuing damage problem). With a single crack, multiple types of future repairs are possible.
To run a crackR analysis, first create an object of class crackR. This is accomplished by first creating an object of class crackRparameters. This can be done by modifying a supplied data set, such as with data(cp7). Use crackRinit() on the crackRparameters object to generate the crackR object. To perform the analysis, use analyze() or crackRmc().
