CONSTRUCTION OF ENTROPY-BASED PRIOR AND POSTERIOR PROBABILITY DISTRIBUTIONS WITH PARTIAL INFORMATION FOR FATIGUE DAMAGE PROGNOSTICS

A method for predicting fatigue crack growth in materials includes providing a prior distribution obtained using response measures from one or more target components using a fatigue crack growth model as a constraint function, receiving new crack length measurements, providing a posterior distribution obtained using the new crack length measurements, and sampling the posterior distribution to obtain crack length measurement predictions.
