Time‐Dependent Reliability
This chapter discusses so‐called 'stochastic', 'time‐dependent' or 'time‐variant' random variables and the related failure probability calculations. It focuses on fatigue reliability and about problems involving dynamic structural behaviour. Fatigue and corrosion are typical examples of strength deterioration. An important strength requirement for structures is fatigue strength. The chapter outlines the essential probabilistic considerations for the analysis of fatigue reliability. In the discretized approach to handling time‐dependent structural reliability problems, the lifetime of the structure is divided into a number of units. When the random nature of a stochastic process does not change with time, it is said to be a '(strictly) stationary' process. This means that all its moments also are independent of time. The chapter describes a number of stochastic processes commonly applied in structural reliability applications.
