Steel Sheet Forming Isotropic Or Anisotropic

Plast 26 9 2010 pp.

Steel sheet forming isotropic or anisotropic.

Due to the different microstructure configurations these two steels show significant differences in plasticity behavior as well as. The international journal of advanced manufacturing technology vol. 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. International journal of plasticity 26.

Rolled sheets elastic deformation is much smaller compared with the plastic deformation so only the anisotropic plasticity is nor mally considered. The damage model is coupled with an elasto plastic material model using anisotropic plasticity hill 48 yield criterion and strain rate dependent isotropic hardening.

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 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. Hybrid beam in this study consists of a number of layers of anisotropic fiber reinforced polymer frp and a layer of isotropic steel sheet.
