ISBN:
Category : Airframes
Languages : en
Pages : 39
Book Description
The methods used in laboratory simulation of random service load conditions, that lead in practice to fatigue failure e.g. aircraft structures, are reviewed. First, the inter-relation of the atmospheric turbulence with the resulting loads on the aircraft are discussed. Then follows an analysis and interpretation of service load histories and a review and comparison of the methods in use for simulating service load spectra of arbitrary and random load sequences. Both random loading, using discrete load levels or analogous random process testing, are discussed. Full scale testing is also reviewed. In appendices, stationary random processes and fewer spectral density functions an evaluation of probability distributions of RMS gust velocities and some damage theories are presented. (Author).
The Analysis of Random Load-time Histories with Relation to Fatigue Tests and Life Calculations

Book Description
This monograph examines the theoretical foundations of the spectral method for fatigue life determination. The authors discuss a rule of description of random loading states with the matrix of power spectral density functions of the stress/strain tensor components. Some chosen criteria of multiaxial fatigue failure are analyzed. The formula proposed in this book enables readers to determine power spectral density of the equivalent history directly from the components of the power spectral density matrix of the multidimensional stochastic process.

Book Description
An investigation has been conducted to determine which combination of method counting and type of load programing best retains the essential fatigue-inducing characteristics of a random time history of stress. In an earlier investigation several time histories were numerically generated and counted by various methods. The data obtained in the earlier investigation were used in this investigation to conduct axial load fatigue tests of 2024-T3 aluminum-alloy sheet specimens with not d edges. The fatigue life obtained from tests using the random peak history was used as a basis of comparison. The elimination of various sized fluctuations, due to the different counting methods, had little, if any, effect on fatigue life in tests using a random sequence of loads. Tests conducted by using ordered loading produced lives greater than the random fatigue life. The value of life in the ordered tests varied with the counting method, with statistical properties of the time history, and probably with the assumptions made in reducing the data to block form.
