Effect of phase angle on the cyclic behavior of AISI 410 alloy [PDF]
MATEC Web of Conferences, 2019 Multiaxial strain-controlled fatigue tests were conducted on AISI 410 according to ASTM 2207-E08 [1] under proportional (phase angle, θ = 90°) and non-proportional (phase angle, θ = 90º) loadings.

Welded joints under multiaxial non-proportional loading [PDF]
Theoretical 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 ...

Thermal Load Model of a Proportional Solenoid Valve Based on Random Load Conditions
Sensors, 2023 Drastic changes in the random load of an electromechanical system bring about a reliability problem for the proportional solenoid valve based on a thermal effect. In order to accurately and effectively express the thermal load of a proportional solenoid valve under random load conditions and to meet the requirements of online acquisition, adaptive ...

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

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

The role of load‐carrying in the evolution of modern body proportions [PDF]
Journal of Anatomy, 2004 AbstractThe first unquestionably bipedal early human ancestors, the species Australopithecus afarensis, were markedly different to ourselves in body proportions, having a long trunk and short legs. Some have argued that ′chimpanzee‐like′ features such as these suggest a ‘bent‐hip, bent‐knee’ (BHBK) posture would have been adopted during gait.

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

Influence of Material Ductility on Fatigue Life under Multiaxial Proportional and Non-Proportional Normal and Shear Stresses [PDF]
MATEC Web of Conferences, 2019 Current experiences show that a non-proportional loading of ductile materials such as wrought steels, wrought aluminium or magnesium alloys, not welded or welded, causes a significant fatigue life reduction under an out-of-phase shear strain or shear ...

Latin American Journal of Solids and StructuresThis paper is concerned with the fatigue prediction models for estimating the multiaxial fatigue limit. An equivalent loading approach with zero out-of-phase angles intended for fatigue limit evaluation under multiaxial loading is used.
