Kinematic hardening and Bauschinger effect

PAMM, 2019
AbstractThis 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, 1956
Abstract 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, 1983
Abstract 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, 1972
Abstract 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, 1981
Abstract 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,

Thermoelectric Power and the Bauschinger Effect

Nature, 1954
IT 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

Effect of grain size on the Bauschinger effect

Metal Science and Heat Treatment, 1964
1. The Bauschinger effect decreases with increasing grain size, probably due to the decrease in the total area of the grain boundaries, on which residual microstresses are created and also due to the possible occurrence of larger deformations within large grains as the result of smaller changes in the surface state of the boundary than in small ...

Nanoscale simulations of Bauschinger effects on a nickel nanowire

Materials Letters, 2008
Abstract In this paper, the Bauschinger effect on a nickel nanowire is studied implementing molecular dynamics simulations in nanoscale. The inter-atomic interactions are represented by employing embedded-atom potential. Initially, the stress–strain curves for tensile and compressive loading are simulated by applying suitable periodic boundary ...

Backstress, the Bauschinger Effect and Cyclic Deformation

Materials Science Forum, 2008
Backstresses or long range internal stresses (LRIS) in the past have been suggested by many to exist in plastically deformed crystalline materials. Elevated stresses can be present in regions of elevated dislocation density or dislocation heterogeneities in the deformed microstructures. The heterogeneities include edge dislocation dipole bundles (veins)
