Bearing behavior and accumulated rotation of modified suction caisson (MSC) in saturated sand under cyclic loading

open access: yesRock and Soil Mechanics, 2021
Modified suction caisson is a new type of suction foundation for offshore wind power engineering. Model tests were carried out to investigate the variation of cumulative rotation angle and its influencing factors of the regular suction caisson (RSC) and

On the applicability of Miner’s rule for multiaxial fatigue life calculations under non-proportional load histories [PDF]

open access: yesFracture 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.

The Strain energy density to estimate lifetime of notched components subjected to variable amplitude fatigue loading [PDF]

open access: yesFracture and Structural Integrity, 2019
In the present paper, the approach based on the strain energy density (SED) averaged over a structural volume is reformulated to estimate the lifetime of notched components subjected to variable amplitude (VA) uniaxial fatigue loading.

Prediction of Fatigue Crack Initiation under Variable Amplitude Loading: Literature Review

open access: yesMetals, 2023
Metallic materials are widely employed in engineering constructions, and one of the most common failure mechanisms in metals is fatigue failure. Even though metal fatigue has been studied for almost 160 years, many problems remain unsolved.

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.

PE-HD fatigue damage accumulation under variable loading based on various damage models

open access: yeseXPRESS Polymer Letters, 2017
Despite numerous studies on fatigue of polymer materials under variable loading, there is little work on highdensity polyethylene (PE-HD). In this context, an experimental analysis for determining the fatigue strength of PE-100, under constant and ...

A statistically self-consistent fatigue damage accumulation model including load sequence effects under spectrum loading [PDF]

open access: yesFracture and Structural Integrity, 2016
A probabilistic methodology is proposed to evaluate fatigue damage accumulation and fatigue lives of specimens under variable amplitude loading. With probabilistic modifications in the present model, the calculative consistency is achieved between ...

Nonlinear waves in solids with slow dynamics: an internal-variable model [PDF]

open access: yes, 2017
In heterogeneous solids such as rocks and concrete, the speed of sound diminishes with the strain amplitude of a dynamic loading (softening). This decrease known as "slow dynamics" occurs at time scales larger than the period of the forcing.

Shortcuts in multiple dimensions: the multiaxial racetrack filter [PDF]

open access: yesFracture 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

Strain range dependent cyclic hardening of 08Ch18N10T stainless steel-experiments and simulations [PDF]

open access: yes, 2019
This paper describes and presents an experimental program of low-cycle fatigue tests of austenitic stainless steel 08Ch18N10T at room temperature. The low-cycle tests include uniaxial and torsional tests for various specimen geometries and for a vast ...
