Damage of materials under proportional loading
Mechanics and Advanced Technologies, 2023 The work is devoted to the study of material damage during elasto-plastic proportional loading, in particular, the influence of two loading mechanisms, detachment and shear, is taken into account. These mechanisms include viscous, brittle, and visco-brittle modes of failure.

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.

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 ...

Multiaxial fatigue assessment of crankshafts by local stress and critical plane approach [PDF]
Fracture and Structural Integrity, 2016 For multiaxially-loaded parts several stress-based fatigue assessment concepts are applicable mostly taking uniaxial test results as basis. These approaches work well in case of proportional loading states, but on contrary, for non-proportional stress ...

Investigation of Proportional and Non-proportional Loadings Using Mohr’s Circle [PDF]
2012 ASEE Annual Conference & Exposition Proceedings, 2020 Investigation of Proportional and Non-proportional Loadings Using Mohr’s Circle ABSTRACTFor time-varying loads, proportional loading refers to the cases where the principal stressesmaintain constant directions and constant ratios of their values; otherwise it is non-proportional,Non-proportional loadings are especially important in the design and ...

Influence of multiaxial cyclic plastic loading on grain boundary misorientation profile in austenitic stainless steel [PDF]
MATEC Web of Conferences, 2019 304LN stainless was subjected to multiaxial loading employing different waveforms and load paths. The grain boundary misorientation profile so obtained post deformation was compared across loading conditions.

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 ...
