“…In this study, the Bodner-Partom material model was employed as a material constitutive model for the computational fatigue crack growth rate evaluation of 7% nickel steel [18]. This model is an elastic-viscoplastic model describing rate-dependent plasticity and creep.…”

“…In the case of the damage mechanism, degradation of elastic stiffness and void/slip growth can be represented by an effective elastic stiffness model and a damage evolution model, respectively. On the basis of the correlation between these two models, the material/structural degradation under various loads, such as fatigue, creep, brittle, and ductile failures, can be evaluated and predicted quantitatively [18][19][20].…”

Abstract:In this study, fatigue crack growth rates (FCGR) of 7% nickel steel at room and cryogenic temperatures were evaluated using damage-coupled finite element analysis (FEA). In order to perform the computational fatigue analysis effectively, methods for coupling damage to FEA are introduced and adopted. A hybrid method including the damage-coupled constitutive model and jump-in-cycles procedure was implemented into the ABAQUS user-defined material subroutine. Finally, the represented method was validated by comparing its results with the FCGR test results for 7% nickel steel under room and cryogenic temperatures. In particular, da/dN versus ∆K and the crack length versus the number of cycles were compared.

Abstract. This article introduces evolutionary algorithms and their utilization in mechanical engineering. First part of this work describes evolutionary algorithms and their characteristics. The main body of evolutionary algorithms, the selection methods for parents and the types of reproduction are explained in the next part of this article. Termination conditions are also discussed. Finally, the application of evolutionary algorithms to a problem in mechanical engineering is described. Thereby, the material parameters for a Bodner-Partom model describing viscoelastoplastic material behavior are determined by fitting data from experiments on Aluminum test samples under tension load.
