Fatigue damage analysis of a riveted steel overhead crane support truss
International Journal of Fatigue, 2019Co-Authors: Petr Lehner, Martin Krejsa, Přemysl Pařenica, Vít Křivý, Jiří BrožovskýAbstract:Abstract A method is proposed to evaluate the residual life of existing steel structures in terms of fatigue damage. The proposed method is demonstrated on the assessment of selected elements in a nearly 100-year old exterior riveted crane support truss. The Monte Carlo method is used to generate a time-dependent load based on the operation of the overhead crane, and detailed numerical modelling based on rainflow counting and the Palmgren-Miner Rule to assess their fatigue resistance and estimate their residual life is evaluated and discussed. This study provides a novel approach to the reliability assessment of riveted joints stressed by cyclic loading and stochastic modelling of the load history of existing structures.

Necessary and sufficient condition for additivity in the sense of the Palmgren–Miner Rule
Computational Materials Science, 2001Co-Authors: Michael TodinovAbstract:Abstract Formal conditions are established regarding the compatibility of the Palmgren–Miner Rule with laws describing the damage development during fatigue. The Palmgren–Miner Rule can be used for fatigue life predictions, if and only if, the damage development rate can be presented as a product of the functions of stress (strain) amplitude and current amount of damage. Important properties of the additive damage development laws are derived and methods are proposed for checking whether a particular damage development law is consistent with the Palmgren–Miner Rule. Some of the reasons for inaccurate fatigue life predictions based on the Palmgren–Miner Rule are rationalised using the derived condition for additivity.
