Book Synopsis Aluminum 7075-T6 Fatigue Data Generation and Probabilistic Life Prediction Formulation by : John G. Kemna
Download or read book Aluminum 7075-T6 Fatigue Data Generation and Probabilistic Life Prediction Formulation written by John G. Kemna and published by . This book was released on 1998-09-01 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life extension of aging fleet aircraft requires an assessment of the safe-life remaining after refurbishment. Risk can be estimated by conventional deterministic fatigue analysis coupled with a subjective factor of safety. Alternatively, risk can be quantitatively and objectively predicted by probabilistic analysis. In this investigation, a general probabilistic life formulation is specialized for constant amplitude, fully reversed fatigue loading utilizing conventional breakdown laws applied to the general probability damage function. Experimental data was collected both as a bench mark data base, as well as an example of the implementation of probabilistic fatigue life prediction. Fully reversed, sinusoidal fatigue testing under load control was carried Out at load levels giving high cycle fatigue lives from 1 x 104 to 5 x 106 cycles. The number of replications at each stress level is greater than currently available in the literature, thereby increasing the confidence of predictions in the long-life domain, as well as extending the statistical basis for probabilistic inference. The load level data sets are interpreted by the probabilistic damage function for life location as well as life shape parameters using maximum likelihood analysis. Homologous life ranking and the minimum entropy hypothesis are investigated as well.

Book Synopsis Room Temperature Tensile Properties of Large 7075-T6 and 7075-T73 Aluminum-alloy Forgings by : D. P. Moon
Download or read book Room Temperature Tensile Properties of Large 7075-T6 and 7075-T73 Aluminum-alloy Forgings written by D. P. Moon and published by . This book was released on 1970 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Room-temperature tensile properties were determined for large 7075-T6 and 7075-T73 aluminum-alloy forgings. Forging sizes ranged from about 1.5 to 15 inches (short-transverse direction) for production forgings and up to 20 inches for step forgings. Heat-treated thickness was 0.75 to 1.000 inch for the T6 temper but ranged up to 10 inches for the T73 temper. Regression coefficients and standard d deviations are presented for three properties (TUS, TYS, and elongation) in each of three test directions. In addition, average values and two statistical minima are tabulated for each property and test direction at each of several discrete sizes, and a comparison is made with the corresponding requirements of Specification MIL-A-22771C(ASG).

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 Influence of Programing Techniques and of Varying Limit Load Factors on Maneuver Load Fatigue Test Results by : Patrick L. Corbin
Download or read book Influence of Programing Techniques and of Varying Limit Load Factors on Maneuver Load Fatigue Test Results written by Patrick L. Corbin and published by . This book was released on 1966 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Variable-amplitude axial-load fatigue tests were conducted on 7075-T6 aluminum-alloy edge-notched specimens having a theoretical elastic stress concentration factor of 4. The load programs were designed to approximate maneuver load spectra. Fatigue life was found to be shorter for random form tests than for block form tests having the same load spectrum. The greatest change in life occurred when the test program contained negative loads. Life for variable-amplitude tests was found to increase as much as 60 percent above the original test life after preloading with a program having a higher limit load factor. The summations of cycle ratios were approximately 2 for tests without negative loads but were approximately 1 for tests with negative loads.

Book Synopsis Effects of Bonding Temperatures on Fatigue Crack Growth by : Rodney L. Wilkinson
Download or read book Effects of Bonding Temperatures on Fatigue Crack Growth written by Rodney L. Wilkinson and published by . This book was released on 1983 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in the crack growth behavior of 7075-T651 aluminum specimens which has been exposed to temperatures between 150 degrees and 355 degrees F (66 deg and 179 deg C) were evaluated. Specimens were fatigue tested at room temperature under flight-by-flight loading conditions. Results from these tests were then compared with data from the baseline (as received) material. Exposure to 250 deg F (121 deg C) or more produced a definite increase in speciment life, apparently due to a decrease in crack growth rates.
Book Synopsis Statistical Analysis of Fatigue Data by : R. E. Little
Download or read book Statistical Analysis of Fatigue Data written by R. E. Little and published by ASTM International. This book was released on 1981 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is commonly assumed in analysing fatigue data that there is a definite functional relationship between life in number of cycles and stress level. However, as has been pointed out several times (1, 2), an examination of the data shows considerable scatter. Even with carefully prepared smooth specimens, all from the same heat of steel, treated in the same manner and tested in the same laboratory, a range of 2 to 1 in number of cycles for failure at the same stress level is normal (1) and a range of 10 to 1 is not unusual (2). If the specimens are tested by different laboratories, slightly varying techniques will introduce further scatter (3).
