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.

Effect of inelastic multiaxial preloading on high cycle fatigue strength
Nihon Kikai Gakkai ronbunshu, 2020 This study investigates an effect of inelastic non-proportional preloading on failure life in a followed high cycle fatigue for two steels, SUS316 stainless and Mod.9Cr-1Mo steels.

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.

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 ...

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 ...

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

Influence of Material Ductility on Fatigue Life under Multiaxial Proportional and Non-Proportional Normal and Shear Stresses [PDF]
MATEC Web of Conferences, 2019 Current experiences show that a non-proportional loading of ductile materials such as wrought steels, wrought aluminium or magnesium alloys, not welded or welded, causes a significant fatigue life reduction under an out-of-phase shear strain or shear ...

A survey on multiaxial fatigue damage parameters under non‐proportional loadings [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2017 AbstractIn this paper, several multiaxial fatigue damage parameters taking into account nonproportional additional hardening are reviewed. According to the way nonproportional additional hardening is considered in the model, the damage parameters are classified into 2 categories: (1) equivalent damage parameters and (2) direct damage parameters.
