Numerical prediction of mechanical properties of dual-phase steel by using multi-phase-field method and homogenization method
In this study, a numerical prediction method by combining the crystal plasticity finite element method, the multi-phase-field method and the homogenization method is developed to predict microstructure formation and mechanical property of the dual-phase (DP) steel efficiently. With the developed method, the austenite – to – ferrite transformation from the deformed austenite phase is simulated and the mechanical properties of the DP steel which includes the predicted microstructure are investigated
Numerical investigations of mechanical stress caused in dendrite by melt convection and gravity
In order to investigate the effects of stress around dendrite neck cased by the convection and gravity on the dendrite fragmentation, the novel numerical model, where phase-field method, Navier-Stokes equations and finite element method are continuously and independently employed, has been developed. By applying the model to the dendritic solidification of Al-Si alloy, the maximum stress variations by melt convection and gravity with dendrite growth were evaluated
