Simulation of Quenching Process Using the Finite Element Method

چکیده
This contribution is concerned with modeling and simulation of quenching employing the finite element method. An anisothermal constitutive model formulated within the framework of continuum mechanics and the thermodynamics of irreversible processes is considered adopting two phases: austenite and martensite. A numerical procedure is developed based on operator split technique associated with an iterative numerical scheme in order to deal with nonlinearities in the formulation. With this assumption, coupled governing equations are solved involving four uncoupled problems: thermal, phase transformation, thermoelastic and elastoplastic behaviors. Classical finite element method is employed for spatial discretization of thermal and thermoelastic uncoupled problems. Progressive induction hardening of steel cylinders is concerned as an application of the general procedure. A comparison between numerical and experimental measures is performed showing good agreements between them.
