Strain localization analysis using a multiscale model [PDF]
, 2007 In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then

Journal of Materials Research and Technology, 2022 A two-dimensional discrete dislocation plasticity model was used to examine the role of strain rate asymmetry on the Bauschinger effect (BE). A simple single crystal single slip plane model was used first to investigate stress–strain response within high

BAUSCHINGER EFFECT DURING SHOCK LOADING [PDF]
, 1992 Parallel shock recovery and wave profile experiments have been performed that exhibit a Bauschinger effect in Si-bronze shocked to 10 GPa. The unloading wave profile in Si-bronze exhibited a quasi- elastic release that had greater departure from the ideal elastic- plastic response than the pure copper samples.

The influence of material anisotropy and spiral welding on tensile strain capacity of spiral welded pipes [PDF]
, 2015 The longitudinal strain capacity of spiral welded pipelines displays to some extents unexplained behaviour. Therefore, they are not (yet) used extensively in offshore applications and harsh conditions, demanding a strain based design. An important factor

Investigation of Bauschinger effect in thermo-plastic polymers for biodegradable stents
Current Directions in Biomedical Engineering, 2017 The Bauschinger effect is a phenomenon metals show as a result of plastic deformation. After a primary plastic deformation the yield strength in the opposite loading direction decreases.

Effects of the grain size and shape on the flow stress: A dislocation dynamics study [PDF]
, 2019 Dislocation dynamics simulation is used to investigate the effect of grain size and grain shape on the flow stress in model copper grains. We consider grains of 1.25-10 $\mu$m size, three orientations (, and ) and three shapes (cube, plate and needles).

Bauschinger effect in uranium. [Rarefaction waves] [PDF]
, 1976 The Bauschinger effect (different elastic-plastic behavior upon unloading) was measured in uranium and a model of the effect developed for use in one-dimensional hydrodynamic codes. Results from plate-impact tests show that rarefaction waves in uranium can be calculated more accurately with this model.
