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 ...

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.

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 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 ...

Bauschinger effect in porous sintered steels
Materials Science and Engineering: A, 2003Abstract The Bauschinger effect was investigated in a sintered Fe–Mo steel by conducting load reversal experiments in tension followed by compression and vice-versa. A significant difference in Bauschinger effect was observed based on the initial direction of loading, with a much stronger Bauschinger effect in the compression–tension than in the ...

Bauschinger effect correspondence of experimental tests
International Journal of Material Forming, 2008Many studies have shown that improvements in the numerical prediction about rolled sheet forming is done through the laws of behaviour increasingly complex, particularly by the combination of isotropic and kinematics hardening (mixed hardening) to take on the Bauschinger effect.

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,

Bauschinger effect in thin metal films
Scripta Materialia, 2005Abstract The Bauschinger effect in thin sputter-deposited Al and Cu films is studied by isothermally deforming the films alternately in tension and compression. Passivated films exhibit an unusual Bauschinger effect with reverse flow already occurring on unloading, while unpassivated films show little or no reverse flows when the film is fully ...

Thermoelectric Power and the Bauschinger Effect
Nature, 1954IT has been proposed1,2 that the Bauschinger effect which occurs in face-centred cubic metals after a plastic strain exceeding 1 per cent might be attributed to the rearrangement of dislocations at the beginning of the reversal of strain. If we rather crudely reckon, that changes of thermoelectric power and electric resistance are measures of the total
