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

A plain linear rule for fatigue analysis under natural loading considering the sequence effect [PDF]
, 2017 Fatigue under variable amplitude loading is currently assessed with the Palmgren-Miner rule in structural standards, ignoring the order of loading, which would require non-linear or mixed rules, especially for the random loading sequences applied to ...

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

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

Cyclic deformation and fatigue data for Ti–6Al–4V ELI under variable amplitude loading
Data in Brief, 2017 This article presents the strain-based experimental data for Ti–6Al–4V ELI under non-constant amplitude cyclic loading. Uniaxial strain-controlled fatigue experiments were conducted under three different loading conditions, including two-level block ...

Damage accumulation of bovine bone under variable amplitude loads
Bone Reports, 2016 Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study on damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear damage accumulation hypothesis, is predictive of fatigue ...
