Abstract

A probabilistic analysis of the fatigue crack growth for RELIABILITY growth calculation on the mechanical component is presented on the basis of fracture mechanics and theory of random process. The loading is postulated to be stationary, narrow-band random Gaussian process and consequently, randomized Paris-Erdogan law is applicable. As a specific problem, a thin plate having a central crack is analyzed by two analytical methods "stochastic averaging (SA)" and "linear FATIGUE DAMAGE accumulation (LFDA)". The aforementioned plate is being analyzed by probabilistic finite element method (PFEM) on the basis of Monte-Carlo simulation. It is shown that SA method presents the most conservative results for brittle materials comparing with FEM and LFDA.
