The chapter presents synthetically the most recent models of the anisotropic plastic behavior. The first section gives an overview of the classical models, In the next step, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively.

Formability of superplastic PbSn60 alloy
Materials Letters, 2005Abstract The forming limit diagram of superplastic PbSn60 alloy was investigated in this paper. The superplastic sheet was bulged using dies with aspect ratios of 1:1, 15:11, 5:3 and 5:2, at the constant gas pressure and at the temperature of 293 K.

The Study of the Impact of Aluminum Formability Parameters on its Stamping Formability
2012To find parameters to estimate stamping formability of aluminum alloy sheet in autobody, simulate the cylinder components stamping process by LS-DYNA software based on dynamic explicit method; Study the impact of the material parameters (Yield stress RPS, hardening exponent n and anisotropy parameter r) and the process parameters (the blank-holding ...

Formability of tailored blanks
Journal of Materials Processing Technology, 1997Abstract Toyota has applied laser-welded tailored blanks for stamping side panel, door inner, front side member and many other auto body panels. Judgment on the formability in actual panel stamping is difficult, because the behavior in press forming of the portion near the weld lines differs from the base material. We have obtained by experiments the

On Formability of MoNiCr Alloy
Advanced Materials Research, 2011The paper deals with recrystallization conditions monitoring for MoNiCr nickel superalloy. The alloy is determined for modern concepts of nuclear reactors in which molten fluoride salts are used in the primary and/or secondary circuit as coolants. It represents a material with high corrosion resistance against fluoride salts and it has very good creep ...

Superplastic Formability Testing
JOM, 1982Incremental strain rate, constant strain rate, constant stress, and cone forming tests were systematically evaluated to determine the superplastic formability of titanium alloys. The need for characterizing the strain and time dependences of superplasticity indices and the inadequacy of incremental strain-rate tests for predicting superplastic forming ...
