Abstract
The paper discusses the problem of linearization for the purpose of simplified calculation of fatigue damage in engineering structures. Specific linearization procedures are proposed that, for some structural models, may be better suited to deal with the problem of fatigue life calculation than the standard mean square stochastic linearization (MSSL). The proposed methods are based on minimizing higher order moments of the linearization error, and it is indicated how the optimal order is linked to the stress exponent of the S-N curve. It is shown by specific example studies that the proposed method may lead to substantial improvement over MSSL in estimating fatigue damage.
