Steel sheet forming isotropic or anisotropic.

The isotropic steel sheet is used in two configurations i in the mid depth of the beam sandwiched between the different frp layers and ii on the side face of the beam.

A method of fabricating an article from a blank of material e g aluminum alloy sheet having anisotropic deformation properties with tooling which has been designed by predicting flow and deformation of the blank using an analysis which decouples the anisotropic deformation properties of the blank. Experimental and numerical investigations on the characterization and prediction of cold formability of two different types of automotive steel sheets a ferritic stainless steel sheet aisi 439 and a dual phase steel sheet dp600 are performed in this study. The damage model is coupled with an elasto plastic material model using anisotropic plasticity hill 48 yield criterion and strain rate dependent isotropic hardening. The type of plastic anisotropy usually desired in sheet metal forming is that the sheet is isotropic in the plane and has an increased strength in the thickness direction which is nor.

Rolled sheets elastic deformation is much smaller compared with the plastic deformation so only the anisotropic plasticity is nor mally considered. Both the isotropic and anisotropic damage models from lemaitre are implemented in an in house implicit finite element code. Some comments on a new anisotropic yield criterion 7 11 natl.
