Formability created by the bauschinger effect
, 2007 This paper describes tests to determine if the Bauschinger effect can act as an additional source of formability, this may possibly explain the enhanced formability observed in incremental sheet forming Small cylindrical products have been made by deep drawing and wall ironing. The upper edges have been necked to various levels of reduction.

Structure Refinement and Bauschinger Effect in fcc and hcp Metals
Metals, 2023 Although the Bauschinger effect has been investigated in some detail in various materials, the number of articles on the effect of grain size is extremely limited, and in current nanostructured materials it is practically absent. Since such materials are

Journal of Materials Research and Technology, 2022 The failure modes and mechanisms of single and polycrystalline aluminum under different stress states are very different. Therefore, molecular dynamics methods were used to study the tension-compression asymmetry and Bauschinger effect of single and ...

Low cycle fatigue properties of extruded magnesium AZ31B [PDF]
FME Transactions, 2022 The low cycle fatigue behavior of magnesium (Mg) AZ31B was observed at room temperature, in which its extrusion process led to differences in tensile and compressive stresses, with an increase in the grain structure and mechanical properties.

Influence of near-surface dislocation cellular structure on Bauschinger effect
Journal of Materials Research and Technology, 2021 Long range internal stress (LRIS) based mechanism and non-LRIS explanation regarding Bauschinger effect are in debate. LRIS is originated from dislocation pile-up and/or cell generated by the pre-loading, therefore dislocation structure characterization ...

Origin of the Bauschinger Effect in Amorphous Solids [PDF]
Physical Review Letters, 2020 We study the structural origin of the Bauschinger effect by accessing numerically the local plastic thresholds in the steady state flow of a two-dimensional model glass under athermal quasistatic deformation. More specifically, we compute the local residual strength, $Δτ^{c}$, for arbitrary loading orientations and find that plastic deformation ...
