led a probe into the influence of material behaviour on the accuracy of springback analysis, and then developed a material model with a consideration of elastoplastic anisotropy and Bauschinger effect
to further improve the accuracy of springback prediction during the hat-shaped forming using high-strength steel sheets.
This approach could also capture the Bauschinger effect
without using the concept of traditional back stresses.
It also proposes a way of representing the Bauschinger effect
Kinematic hardening is characterized by a number of phenomena under cyclic loading, such as the Bauschinger effect
, cross effects, permanent softening and work-hardening stagnation .
is not taken into consideration.
consideration, ...) and for twist springback this need even increases.
A Von-Mises' yield criterion, isotropic strain hardening with the PrandtlReuss theory has been taken into the consideration with Bauschinger effect
and plane stress conditions.
It assumes the total stress range is equal to twice the yield stresses, so that Bauschinger effect
Typically within the former parameter, the issue of isotropic and kinematic hardening (Vladimirov et al., 2009), Bauschinger effect
(Gau and Kinzel, 2001), evolution of elastic properties (Sun and Wagoner, 2011) and elastic and plastic anisotropy (Li et al., 2002) were raised.
This is known as the Bauschinger effect
, a well-known phenomenon.
