Simulation Based Probabilistic Assessment of Fatigue Life of Structural Components

Computer simulations based on the Monte Carlo method are often used for the probabilistic assessments of fatigue lives of structures and mechanical components. This is due to relatively easy simulation and reliability calculation procedure, particularly if the direct Monte Carlo method is applied. The only disadvantage of such a method is the necessity of large number of repetitions required for a high level of reliability. Useful tips enabling the decrease of the number of samplings in the simulation procedure and preserving the required reliability level are the subject of the discussion presented below.
