Bauschinger effect during alternating deformation
Izvestiya. Ferrous Metallurgy, 2022The Bauschinger effect is a phenomenon of a decrease in material resistance to small plastic deformations after preliminary plastic deformation of the opposite direction, discovered in 1881. This effect is of great importance and is used, in particular, in studying the fatigue strength of materials under alternating loads.

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.

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.

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 copper
Acta Metallurgica, 1981Abstract A study of the Bauschinger effect in pure copper shows that by comparison with dispersion hardened copper the effect is very small and independent of temperature. This suggests that the obstacles to flow are deformable. A simple composite model based on this principle accounts for the data semi-quantitatively and also accounts for the stored
