Strain gradient plasticity under non-proportional loading [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 A critical examination is made of two classes of strain gradient plasticity theories currently available for studying micrometre-scale plasticity. One class is characterized by certain stress quantities expressed in terms of increments of strains and their gradients, whereas the other class employs incremental relationships between all stress ...

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

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

Nonlinear kinematic hardening under non-proportional loading [PDF]
, 1979 Nithin the framework of conventional plasticity theory, it is first determined under which conditions Helan-Prager's and Ziegler's kinematic hardening rules result in identical material behaviour. Next, assuming initial isotropy and adopting the von Mises yield criterion, a nonlinear kinematic hardening functionis proposed for prediction of metal ...

Thermomechanically coupled model for non-proportional loading in SMAS [PDF]
, 2016 In this work, a new 3D thermomechanically coupled phenomenological model is proposed for SMAs. SMA behavior is described through several strain mechanisms, each associated with its proper internal variables. Forward and reverse transformation are allowed to take place simultaneously with martensite variants reorientation. This model is built to capture

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 ...

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.
