Vladimirov in pietryga mp reese s 2010 anisotropic finite elastoplasticity with nonlinear kinematic and isotropic hardening and application to sheet metal forming. 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. Technology and machine tools for cold metal forming tpr 2000 cluj napoca romania 11 12. The damage model is coupled with an elasto plastic material model using anisotropic plasticity hill 48 yield criterion and strain rate dependent isotropic hardening.

Hybrid beam in this study consists of a number of layers of anisotropic fiber reinforced polymer frp and a layer of isotropic steel sheet. Both the isotropic and anisotropic damage models from lemaitre are implemented in an in house implicit finite element code.
