This book was released on 2010 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The total fatigue life cycle of aluminium alloys was investigated using finite element analysis. The effect of stress concentration factors on fatigue life was analyzed using pre-post MSC.Patran and MSC.Nastran for stress analysis whereas MSC.Fatigue was used for fatigue analysis. The aluminium alloys was selected for this project since it is typically used to make most of the mechanical components. Six different models with varies stress concentration factors were analyzed. The model used in this study is standard tensile specimens in accordance to the ASTM (American Society for Testing and Materials). The stress amplitude curve, S as a function of number of cycles to failure, N was plotted in order to compute the total life cycles of the models and endurance limit as well. Based on the results, it shows that the model with higher stress concentration factor, Kt have lower life cycles.

This book was released on 2018-06-30 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capabilities of a plasticity-induced crack-closure model to predict small- and large-crack growth rates, and in some cases total fatigue life, for four aluminum alloys and three titanium alloys under constant-amplitude, variable-amplitude, and spectrum loading are described. Equations to calculate a cyclic-plastic-zone corrected effective stress-intensity factor range from a cyclic J-integral and crack-closure analysis of large cracks were reviewed. The effective stress-intensity factor range against crack growth rate relations were used in the closure model to predict small- and large-crack growth under variable-amplitude and spectrum loading. Using the closure model and microstructural features, a total fatigue life prediction method is demonstrated for three aluminum alloys under various load histories. Newman, J.

Download or read book Towards a Unified Fatigue Life Prediction Method for Marine Structures written by Weicheng Cui and published by Springer. This book was released on 2014-11-04 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to apply the damage tolerance design philosophy to design marine structures, accurate prediction of fatigue crack growth under service conditions is required. Now, more and more people have realized that only a fatigue life prediction method based on fatigue crack propagation (FCP) theory has the potential to explain various fatigue phenomena observed. In this book, the issues leading towards the development of a unified fatigue life prediction (UFLP) method based on FCP theory are addressed. Based on the philosophy of the UFLP method, the current inconsistency between fatigue design and inspection of marine structures could be resolved. This book presents the state-of-the-art and recent advances, including those by the authors, in fatigue studies. It is designed to lead the future directions and to provide a useful tool in many practical applications. It is intended to address to engineers, naval architects, research staff, professionals and graduates engaged in fatigue prevention design and survey of marine structures, in fatigue studies of materials and structures, in experimental laboratory research, in planning the repair and maintenance of existing structures, and in rule development. The book is also an effective educational aid in naval architecture, marine, civil and mechanical engineering.

Download or read book Use of Small Fatigue Crack Growth Analysis in Predicting the S N Response of Cast Aluminum Alloys written by JW. Jones and published by . This book was released on 2000 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of a material model to estimate the S-N response of a cast aluminum alloy is described. An important requirement of such a model is sensitivity to processing effects such as solidification time and subsequent material characteristics such as secondary dendrite arm spacing (SDAS), strength, and porosity. It has been speculated that the fatigue properties of aluminum castings are dominated by the propagation of cracks which initiate from microshrinkage pores ranging in size from ~ 10 to 1000 ?m. A model was developed that calculates fatigue life based on small crack growth rates measured in cast 319 aluminum specimens with two different solidification times. Results from this small crack model are compared with predictions from a traditional LEFM model using long-crack data and measured thresholds.

This book was released on 2013-04-22 with total page 101 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 1997 in the subject Engineering - Mechanical Engineering, , language: English, abstract: A study of metal cumulative fatigue damage at multilevel stress programs using 2024- T 4 AI -Alloy is carried out in this investigation. Specimens are designed and fabricated. The tests are performed under multiaxial fatigue in phase combined loading bending and torsion, with zero mean stress (R=-l) at room temperature. Five groups of multiaxial fatigue experiments are performed, constant amplitude, linear increasing and decreasing, Low-High loading sequence, High-Low loading sequence and equivalent flight loading fatigue. Prediction of life specimens are studied at three methods: Palmgren-Miner, Corten - Dolan, and Marsh. The methods are conservative to some specimens and non-conservative to another. The effects of stage life (ns) have been examined and fatigue life of specimens are decreased when the stage life is decreased. Comparisons between High-Low & Low-High loading sequences in fatigue life (multi stress level) have been investigated. The Low-High loading sequence is less dangerous than High-Low loading sequence at the same stress range (equal loading stages). Studies the effect of stress range fatigue life have been investigated and the fatigue life is decreased with increasing the stress range fatigue (having the same lowest stress). For the fatigue of equivalent flight loading, the life is depend basically on stress range and the cruising interval this two parameters have been studied.

Download or read book Prediction of Low Cycle Fatigue Life by Acoustic Emission Part 1 written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-cycle fatigue tests were conducted by tension-compression until rupture, on a 2024-T3 aluminum alloy sheet. Initial crack sizes and orientations in the fatigue specimens were found to be randomly distributed. Acoustic emission was continuously monitored during the tests. Every few hundred cycles, the acoustic signal having the highest peak-amplitude, was recorded as an extremal event for the elapsed period. This high peak-amplitude is related to a fast crack propagation rate through a phenomenological relationship. The extremal peakamplitudes are shown by an ordered statistics treatment, to be extremally distributed. The statistical treatment enables the prediction of the number of cycles left until failure. Predictions performed a-posteriori based on results gained early in each fatigue test are in good agreement with actual fatigue lives. The amplitude distribution analysis of the acoustic signals emitted during cyclic stress appears to be a promising nondestructive method of predicting fatigue life.
