Available in PDF, EPUB and Kindle. Book excerpt: This investigation was made to determine whether alternate periods of load and rest would have the same effect as continuous loading on the deformation characteristics of metals at elevated temperatures. Constant-load and cyclic-load creep tests were made on sheet specimens of 24S-T3 and 24S-T81 aluminum alloys at 300 F, SAE 4130 steel at 800 F, and AISI 310 stainless steel at 1500 F. The test results indicate that under the conditions of these tests cycling the load did not increase the rate of creep of the materials tested. Also since none of the cyclic-load tests had creep rates less than one half the rate of the constant-load test, there was no evidence of recovery taking place during the low-load part of the cycle. Specimens of 24S-T3 showed less creep deformation during the first ten hours of the tests than did the corresponding tests of 24S-T81 alloy, although subsequent creep rates were essentially the same. The data obtained, although incomplete, indicate that it is probably safe to design for cyclic-load conditions using data from constant-load tests.

Download or read book Stress Analysis for Creep written by J.T. Boyle and published by Elsevier. This book was released on 2013-10-22 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress Analysis for Creep focuses on methods on creep analysis. The book first ponders on the occurrence of creep in mechanical engineering components, including background to stress analysis for creep and general-purpose computer programs for creep analysis. The text presents a phenomenological description of creep. The phenomenon of creep, physical mechanisms of creep, convenient uniaxial constitutive relationships, and creep rupture are described. The book also explains simple component behavior, creep under multiaxial states of stress, and stress analysis for steady creep. The text focuses on reference stress methods in steady creep. Reference stresses for combined loading with a power law; non-isothermal power-law creep; reference temperatures; and approximate reference stress methods are elaborated. The text also focuses on stress analysis for transient creep; approximate solution of transient creep problems; and creep buckling and rupture. The text highlights the design for creep, including material data requirements and constitutive modeling for design; verification and qualification of stress analysis; and design methodology. The book is a good source of data for readers wanting to study creep analysis.

This book was released on 1976 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept that creep response is the result of a transient approach to a minimum strain rate continuously modified by accumulating damage has been investigated using high precision creep data. It was considered that the accumulated creep strain might be some measure of internal damage and curves of log creep strain rate against creep strain are shown to exhibit linearity at higher strain levels consistent with these assumptions. A modified steady-state relationship has been derived and the variation of its two coefficients with stress and temperature explored. The effect of load and temperature history is illustrated by varying the prior heating time, by cyclic load testing and by step reductions in load level, and it is tentatively concluded that tests of these types may be correlated with the appropriate continuous creep test by using the modified steady-state relationship with corrections for differences in accumulated creep strain and time at temperature.
