An Abaqus plug-in to simulate fatigue crack growth
نویسندگان
چکیده
Fatigue crack propagation is an important consideration in evaluating the design life of engineering components, especially energy and transport industries. Despite its importance, fatigue analyses are not usually supported by commercial Finite Element (FE) codes; fact, most FE codes require addition costly plug-ins to perform growth simulations. Therefore, this paper introduces a new, freely distributed plug-in simulate with code Abaqus. The includes five different models relies on extended method propagation. limited 2D analyses, but covers all necessary steps for simulations, from creating geometry job submission post-processing. implementation validated comparing predictions analytical experimental results. Finally, we hope that simplicity fact it will make useful simulation tool industrial, research educational purposes.

متن کاملVacuum Levels Needed to Simulate Internal Fatigue Crack Growth in Titanium Alloys and Nickel-base Superalloys: Thermodynamic Considerations (preprint)
Prior studies have examined fatigue growth of surface cracks in vacuum to simulate sub-surface growth in Ti-alloys and Ni-base superalloys. Even with the highest vacuum level attained using “state-of-the-art” pumps, it is unclear if conditions of internal crack growth are truly simulated. We consider thermodynamics of the oxidation process to help answer this question. This consideration helps ...

متن کاملFatigue Crack Growth Monitoring of an Aluminum Joint Structure
The detection, location, and sizing of a fatigue crack emanating from a fastener hole in an aluminum plate is investigated. Two linear arrays of surface mounted piezoelectric disk transducers send and receive ultrasonic guided waves that are transmitted, reflected, and scattered by both the joint geometry and the fatigue crack. A tomography algorithm is used to detect and locate the crack. Ampl...
متن کاملThermal activation of fatigue crack growth: analysing the mechanisms of fatigue crack propagation in superalloys
A method for deriving apparent activation energies, Eapp, for fatigue crack growth (FCG) is presented. It is shown how these Eapp values can be used to analyse the main underlying mechanism causing the progression of the crack. The Eapp values for fatigue crack growth in air and vacuum, and with and without a dwell are obtained for a range of Ni based superalloys for turbine disc applications. ...
