TLDR
In this article, the authors present a shorter version of a more detailed treatise by the author, which consists of two parts: the empirical determination of certain characteristics of a material by means of a relatively small number of standard tests, and the arithmetical application of the results obtained to arbitrary loading histories.Abstract:
The present work is a shorter version of a more detailed treatise by the author (1)∗. The method consists of two parts: the empirical determination of certain characteristics of a material by means of a relatively small number of well defined standard tests, and the arithmetical application of the results obtained to arbitrary loading histories. The following groups of parameters are thus taken into account: the variations of the mean stress; the interaction of these variations and the superposed oscillating stresses; the spectrum of the oscillating-stress amplitudes; the sequence of the oscillating-stress amplitudes.read more

Unconventional reflections on damage accumulation
TL;DR: In this article, the implications of Miner's rule are revealed a priori as leading to inaccurate and even contradictory results, due to incompatibility with basic physical laws, and a part of these imperfections can be ruled out by a new method of accumulated damage calculation.

A weight function method for multiaxial low-cycle fatigue life prediction under variable amplitude loading:
TL;DR: In this article, a weight function based on strain parameters is proposed to determine the critical plane in low-cycle fatigue region under both constant and variable amplitude tension-torsion loadings.
