Finite element method coupled with a numerical cellular automaton model to simulate the residual stress of dual phase DP600 steel Nd:YAG laser welding
Abstract
Colloque avec actes et comité de lecture. Internationale. ; International audience ; A sequentially coupled thermo-mechanical model has been developed to investigate the residual stresses of DP600 dual phase steel welded by a Nd:YAG laser process. A numerical cellular automaton (CA) model has been firstly built to simulate the microstructure evolution during a laser welding. The obtained CA microstructure orientation results are input into a finite element model (FEM) as material anisotropic parameters together with a corresponding constitutive law characterizing the material behavior taking into account the dual phase ferrite-martensite hardening, the temperature sensitivity and the strain rate influence. The numerical residual stresses predicted by the proposed coupled CA-FEM model have variations close to those of experimental observation. The anisotropy of dual phase DP600 steel has been analyzed both from the solidification process using the numerical CA model and from the base metal thermo-mechanical behavior influence using a sequentially coupled thermal-elastic-plastic model and a plane anisotropy theory. It is observed that the residual stress longitudinal to welding direction is more influenced by the material anisotropy and the temperature sensitivity. The analysis of DP600 coupled anisotropy model consists of two parts: I. Anisotropy of weld: The developed numerical CA model take into account welding temperature field history, the nucleus density, nucleus position and diffusion behavior. The obtained dendrites solidification directions are applied to analyze the microstructure evolution during the welding process and to compute the orthotropic elastic constants of DP600 weld. The martensitic phase properties and the orientations of the weld material are input into a FEM taking into account the corresponding anisotropy. II The anisotropy of base metal: A lot of specimens undergoing tensile tests along three different orientations corresponding to 0°, 45°and 90° with the plate rolling direction have ...
