Differences in the response to in-phase and out-of-phase multiaxial high-cycle fatigue loading
Fracture and Structural Integrity, 2019 This paper discusses the phase shift effect occurring between two and more load channels of multiaxially loaded specimens. The discussion concludes that there is an extreme shortage of good experimental data that would prove the existence and the trend ...

On the applicability of Miner’s rule for multiaxial fatigue life calculations under non-proportional load histories [PDF]
Fracture and Structural Integrity, 2017 Fatigue design routines and computer codes must use some damage accumulation rule to deal with variable amplitude loadings (VAL), usually Palmgren-Miner (or Miner’s) linear rule for lack of a clearly better option.

Algorithm for Non-Proportional Loading in Sequentially Linear Analysis
Proceedings of the 9th International Conference on Fracture Mechanics of Concrete and Concrete Structures, 2016 Sequentially linear analysis (SLA) is an alternative to the Newton-Raphson method for analyzing the nonlinear behavior of reinforced concrete and masonry structures. In this paper SLA is extended to load cases that are applied one after the other, for example first dead load and then wind load. It is shown that every nonlinear analysis step can be made

On the assessment of multiaxial fatigue damage under variable amplitude loading [PDF]
Fracture and Structural Integrity, 2016 In this work, the performance of the SSF criterion is evaluated under variable amplitude loading conditions. The main objective was to inspect the validity of the hypothesis in which the SSF damage map remains valid for any high strength steel.

Evaluating shakedown under proportional loading by non-linear static analysis
, 2003 A lower bound method for calculating shakedown loads under proportional loading by static non-linear finite element analysis is presented. Stress fields obtained by static analysis and stress superposition are substituted into Melan's lower bound ...

A plasticity model with yield surface distortion for non proportional loading [PDF]
International Journal of Plasticity, 2001 In order to enhance the modeling of metallic materials behavior in non proportional loadings, a modification of the classical elastic-plastic models including distortion of the yield surface is proposed. The new yield criterion uses the same norm as in the classical von Mises based criteria, and a "distorted stress" Sd replacing the usual stress ...

Shortcuts in multiple dimensions: the multiaxial racetrack filter [PDF]
Fracture and Structural Integrity, 2015 Filtering techniques have been proposed for multiaxial load histories, usually aiming to filter out non-reversals, i.e. sampling points that do not constitute a reversal in any of its stress or strain components. However, the path between two reversals

Sharp three-dimensional notches under combined nominal normal and shear fatigue loading [PDF]
Fracture and Structural Integrity, 2017 Many engineering structures are exposed to non-proportional fatigue loading. However, at the critical location of crack initiation, often only one of the load sequences dominates – the individual load cases result in different crack initiation sites ...

Multiaxial fatigue strength under non-proportional loading of additively manufactured notched components of Ti-6Al-4V [PDF]
MATEC Web of Conferences, 2019 In this study fatigue tests have been conducted on additively manufactured notched specimens made of titanium alloy Ti-6Al-4V under uniaxial loading and multiaxial non-proportional loading. Laser powder bed fusion technique has been employed to fabricate
