Origin of the Bauschinger effect in a polycrystalline material [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2017 There is a long and lively debate in the literature about the origin of the Bauschinger effect in polycrystalline materials, the most widely accepted explanation being the easier movement of dislocations during reverse loading causing the reduction of ...

Analysis of the bauschinger effect
Acta Metallurgica, 1986Abstract Continuum and microstructural theories of the Bauschinger effect are reviewed in relation to present understanding of the role of internal stresses in work hardening. Influences of internal stress on stress-strain relationships observed in monotonic and reversed straining can be described in terms of a combination of isotropic and kinematic ...

Acta Materialia, 1996
Abstract An experimental investigation of the “Bauschinger effect” in materials under dynamic loading conditions is presented. In this study, a tension split Hopkinson bar with a momentum trap is used to subject a tensile specimen to a single high strain-rate tension pulse of known magnitude and duration.

For plastic materials, an increment of the non-elastic strain of an opposite sign is observed experimentally irrespective of the plastic strain quantity preceding unloading already in the case of full unloading. This increment usually exceeds the size of the order of elastic hysteresis.

The Bauschinger Effect in AA 6111
Materials Science Forum, 2006In this paper, tension compression tests are carried out on AA6111 specimens in order to characterize the internal stress. The impact of the microstructure is investigated by applying a variety of ageing conditions to the specimens prior testing. It is shown that the Bauschinger effect depends strongly on the precipitation state.

Kinematic hardening and Bauschinger effect
PAMM, 2019AbstractThis paper studies a single crystal subjected to anti‐plane shear‐controlled load reversal within the thermodynamic dislocation theory. Numerical simulations of the governing equations demonstrate the size‐dependent kinematic hardening and the Bauschinger effect. Both are caused by the excess dislocations.

The Bauschinger Effect on Columns
Journal of Applied Mechanics, 1956Abstract Earthquakes or the passing shock wave of an atomic blast may cause tensile yield in members before collapse in compression (1). In order to examine the effect of this reversal, the reduction of compressive properties of structural steel are analyzed after a variety of tensile pre-strains and these properties are applied to ...

Intergranular constraint and the Bauschinger effect
Materials Science and Engineering, 1983Abstract The Bauschinger effect in f.c.c. polycrystals due to intergranular constraint was evaluated on the basis of the self-consistent model proposed by Kroener and by Budianski and Wu, taking into account the effect of non-directional linear work hardening.

The Bauschinger effect and discontinuous yielding
Philosophical Magazine, 1972Abstract Although the most popular definition of the Bauschinger effect refers to the lowering of the yield stress for reversed loading, the effect is more complex than was previously thought and it involves not only the initial yield strength, but the entire stress—strain curve after prestraining.

The bauschinger effect in Zircaloy-2
Journal of Nuclear Materials, 1981Abstract The Bauschinger effect in Zircaloy-2 has been investigated at room temperature using (a) specimens cut from the L and ST directions of a thick, rolled slab, and (b) specimens machined from swaged rod. The blocks of material, from which the slab specimens were cut, received compressive prestrains of up to 3.8%, in either the L or ST direction,
