Deformation and Degradation of Superelastic NiTi Under Multiaxial Loading [PDF]

open access: yesSSRN Electronic Journal, 2018
The degradation of the superelastic properties of a commercial NiTi alloy are studied during uniaxial, biaxial and load-path-change cycling performed in-situ with synchrotron X-ray diffraction. Careful examination of the diffraction pattern during uniaxial loading shows the R-phase as a transition between the austenite and the B19' martensite ...

Fatigue Testing and Evaluation of Fatigue Strength under Multiaxial Stress State; Why do we need fatigue testing?

open access: yesMATEC Web of Conferences, 2018
Types of multiaxial fatigue tests and their experimental results are presented in this paper. There are typical three types in multiaxial fatigue tests: the combining push-pull and reversed torsion loading test using hollow cylinder specimen, the biaxial

Welded joints under multiaxial non-proportional loading [PDF]

open access: yesTheoretical and Applied Fracture Mechanics, 2018
El presente documento examina el comportamiento a la fatiga de una junta tubular en T soldada en filete en el denominado componente estructural H de un pulverizador agrícola. Dado que las mediciones experimentales, realizadas en algunas ubicaciones de control del equipo, han resaltado un campo de tensión/deformación de naturaleza aleatoria, aquí se ...

Numerical implementation of a multiaxial cyclic plasticity model for the Local Strain Method in low cycle fatigue [PDF]

open access: yesFracture and Structural Integrity, 2014
Very often computations on structural elements or machine components subjected to variable loading require using an advanced finite element model. This paper reports the numerical implementation of a model for multiaxial cyclic elasticplastic behaviour ...

Comparative study of multiaxial fatigue methods applied to welded joints in marine structures [PDF]

open access: yesFracture and Structural Integrity, 2016
Marine structures are particularly prone to action of waves, winds and currents with stochastically varying composition, intensities and directions. Therefore, resultant stresses may cause multiaxial fatigue in specific welded structural details. For the

Evaluation of multiaxial low cycle fatigue life under non-proportional loading considering effect of mean strain (Loading simulated thermal fatigue due to temperature fluctuation in junction piping)

open access: yesNihon Kikai Gakkai ronbunshu, 2020
In a pressure vessel, a heat exchanger and a junction piping where cold and hot water are mixed, temperature fluctuation yields multiaxial stress and random amplitude loading conditions.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.
