Fracture Mechanics

In this study, weakly-singular SGBEM for fracture analysis of three-dimensional structures considering rotational inertia and gravitational forces are developed, and some numerical examples are presented to verify this approach and results are compared with benchmark solutions.

an intelligent digital-twin-based strategy for the inspection and maintenance of aircraft skin cracks, which takes advantages of the reduced order fracture mechanics simulation, the fatigue crack growth model, the data of crack length inspections, and the framework of the dynamic Bayesian network, comprehensively considering the uncertainties of the initial crack size, crack growth model parameters, differential pressure load in flight, measurement error etc.
