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.

Brittle compressive failure of ice: proportional straining vs proportional loading
Journal of Glaciology, 2006 AbstractProportional straining experiments have been performed on columnar-grained S2 freshwater ice biaxially compressed across the columns at –10°C at a strain rate of (4.5 ± 1.5) × 10–3 s–1. The results are compared with those obtained earlier (Iliescu and Schulson, 2004) from the same kind of material deformed to terminal failure under the same ...

Observations and modelling of non-proportional mixed mode cyclic loading [PDF]
MATEC Web of Conferences, 2019 Under non-proportional mixed-mode loading conditions at the crack tip, some observations are reported. They are limited to cases of cylindrical specimens under normal force and torsion. The fatigue cracks have been initiated by the same loading for which

Multiaxial fatigue strength under non-proportional loading of additively manufactured notched components of Ti-6Al-4V [PDF]
MATEC Web of Conferences, 2019 In this study fatigue tests have been conducted on additively manufactured notched specimens made of titanium alloy Ti-6Al-4V under uniaxial loading and multiaxial non-proportional loading. Laser powder bed fusion technique has been employed to fabricate

Strain hardening under non-proportional loading in polycrystalline aluminum alloys
Engineering Transactions, 2014 In the paper it is postulated that the so-called common slip domains influence the character of the strain hardening phenomena for complex loading paths.

Cyclic Deformation and Low-Cycle Fatigue for 316LN Stainless Steel under Non-proportional Loading [PDF]
MATEC Web of Conferences, 2019 The effects of loading path and strain amplitude ratio on the cyclic behavior and fatigue life were investigated on a 316LN nuclear grade stainless steel employing a series of symmetrically strain-controlled fatigue tests at room temperature. The loading

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 ...
