Book Synopsis Effects of Changing Stress Amplitude on the Rate of Fatigue-crack Propagation in Two Aluminum Alloys by : C. M. Hudson
Download or read book Effects of Changing Stress Amplitude on the Rate of Fatigue-crack Propagation in Two Aluminum Alloys written by C. M. Hudson and published by . This book was released on 1961 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of fatigue tests with specimens subjected to constant amplitude and two-step axial loads were conducted on 12-inch-wide sheet specimens of 2024-T3 and 7075-T6 aluminum alloy to study the effects of a change in stress level on fatigue-crack propagation. Comparison of the results of the tests in which the specimens were tested at first a high and then a low stress level with those of the constant-stress-amplitude tests indicated that crack propagation was generally delayed after the transition to the lower stress level. In the tests in which the specimens were tested at first a low and then a high stress level, crack propagation continued at the expected rate after the change in stress levels.

Book Synopsis Effect of Microstructure on Fatigue Crack Growth of 7XXX Aluminum Alloys Under Constant Amplitude and Spectrum Loading by : T. H Sanders (Jr)
Download or read book Effect of Microstructure on Fatigue Crack Growth of 7XXX Aluminum Alloys Under Constant Amplitude and Spectrum Loading written by T. H Sanders (Jr) and published by . This book was released on 1978 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: An investigation was made to identify microstructural features which control the fatigue crack growth characteristics of 7XXX aluminum alloys. Constant amplitude and simple overload tests were conducted in humid air on controlled microstructural variations of alloys 7075 and 7050. Results indicated that relative influence of different microstructural features and ranking of the alloys based on fatigue crack propagation resistance depend on loading conditions.

This book was released on 1979 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue crack propagation of high strength aluminum alloys subjected to variable amplitude loading is strongly influenced by sequence effects. For a reliable evaluation of the sequence effects, an exact knowledge of the changes in the mechanical and physical conditions of the material surrounding the crack becomes necessary. To allow greater understanding of these processes, two aspects which are based on recent crack propagation investigations are considered in the present study.

Book Synopsis The Influence of Hold Times on Fatigue Crack Growth of Aluminum Alloys by : H. L. Marcus
Download or read book The Influence of Hold Times on Fatigue Crack Growth of Aluminum Alloys written by H. L. Marcus and published by . This book was released on 1980 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of the research on fatigue crack growth in aluminum alloys are described in three general areas. The first relates the influence of hold time at an underload that follows an overload on the fatigue crack growth retardation behavior of the 7075 and 2219 aluminum alloys. A very distinct effect on retardation with hold time is observed. The effect is microstructure dependent with the time dependence behavior extending over a longer period for the high strength materials. This well-defined time dependence clearly shows that lifetime predictions based on accelerated short hold time tests could be very non-conservative. The influence of humidity was also determined using vacuum as a reference environment. The second aspect of the research investigated the nature of the residual displacement, d, that leads to the crack closure phenomena. The last major emphasis was to investigate how gaseous environments interact with fatigue crack growth in aluminum alloys. Combined AES/SIMS studies were made of fracture surfaces taken from fatigue crack growth specimens fatigued in vacuum and subsequently exposed to and fatigued in a range of environments.

Book Synopsis Fatigue Crack Growth Behavior of 7XXX Aluminum Alloys Under Simple Variable Amplitude Loading by : PE. Bretz
Download or read book Fatigue Crack Growth Behavior of 7XXX Aluminum Alloys Under Simple Variable Amplitude Loading written by PE. Bretz and published by . This book was released on 1984 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This investigation examines the influence of temper and purity on the fatigue crack growth (FCG) behavior of four 7XXX aluminum alloys (7075-T6, 7075-T7, 7050-T6, 7050-T7) tested using a periodic single overload spectrum at low stresses. The loading sequence consists of a periodic single overload spike occurring once every 8000 constant amplitude cycles; the overload spike is 1.8 times the constant amplitude load peak. All tests have been performed in high humidity (>90% relative humidity) air at a frequency of 20 Hz and a constant amplitude load ratio of R = 0.33. The observed microstructural effects on transient (that is, spectrum) FCG behavior are contrasted with those for steady-state (constant load amplitude) fatigue performance.
