On reliability of systems with moving material subjected to fracture andn instability

摘要

The reliability of systems with moving cracked elastic and isotropic material is considered. The material is modeled as a moving plate which continually has a crack on the edge. The plate is subjected to homogeneous tension acting in the traveling direction and the tension varies temporally around a constant value, the set tension. The tension and the length of the crack are modeled by an Ornstein-Uhlenbeck process and an exponential Ornstein-Uhlenbeck process, respectively. Failure is regarded
