dc.description.abstractIn order to present better prediction capability in computational analysis, mechanical properties of the dualphase
high strength steel have been characterized especially for anisotropy as well as the Bauschinger and
transient behavior. As for the anisotropy, the non-quadratic anisotropic yield function Yld2000-2d has been
utilized and its material parameters have been obtained using the uni-axial tension tests as well as the hydraulic
bulge test. To measure the hardening behavior including the Bauschinger and transient behavior, a newly
developed test method has been applied for the uni-axial tension/compression and compression/tension tests,
in which solid blocks along the both sides of the sheet specimen prevent buckling. From the tension/compression
curves, the equations to describe isotropic and kinematic hardening behavior have been obtained. The modified
Chaboche model has been confirmed to well represent the hardening behavior including the Bauschinger
and transient behavior.
