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.

Steel sheet forming isotropic or anisotropic. Both the isotropic and anisotropic damage models from lemaitre are implemented in an in house implicit finite element code. Rolled sheets elastic deformation is much smaller compared with the plastic deformation so only the anisotropic plasticity is nor mally considered. Technology and machine tools for cold metal forming tpr 2000 cluj napoca romania 11 12. The method calculates the response of a small amount of the blank using crystal plasticity.

Due to the different microstructure configurations these two steels show significant differences in plasticity behavior as well as. Vladimirov i n pietryga m p reese s anisotropic finite elastoplasticity with nonlinear kinematic and isotropic hardening and application to sheet metal forming int. 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. Hybrid beam in this study consists of a number of layers of anisotropic fiber reinforced polymer frp and a layer of isotropic steel sheet.

The damage model is coupled with an elasto plastic material model using anisotropic plasticity hill 48 yield criterion and strain rate dependent isotropic hardening.
