With this ICME workflow, effective properties at the macroscale could be obtained by taking microstructure morphology and orientation into consideration. An ICME-based vertical integration workflow in two stages is proposed. The flow curve from virtual test simulation showed good agreement with the flow curve obtained with tensile test in Gleeble ®. FEM-based virtual uniaxial tensile test with Abaqus ® software was used to calculate the effective macroscale flow curves from the phase-field simulated microstructure. Asymptotic homogenization implemented in Homat ® software was used to calculate the effective macroscale thermo-elastic properties from the phase-field simulated microstructure. A single scaling factor introduced in JMatPro ® software minimized the deviation between calculations and experiments. The phase fractions and the phase transformation kinetics simulated by phase-field method agreed well with experiments. The austenite-to-ferrite and austenite-to-bainite transformations during cooling at HAZ were simulated using the Johnson–Mehl–Avrami–Kolmogorov (JMAK) equation implemented in JMatPro ® software and with phase-field modeling implemented in Micress ® software. The resulting phase transformations and microstructure were studied experimentally.
JMATPRO SOFTWARE SIMULATOR
The time–temperature profile at HAZ obtained from FEM simulation was physically simulated using Gleeble 3800 ® thermo-mechanical simulator with a dilatometer attachment. The macroscale simulation of the welding process was performed with finite element method (FEM) implemented in Simufact Welding ® software and was experimentally validated. In addition to the evolution of temperature, stress and strain fields, we can also obtain information on the resulting microstructure (phase composition and grain size), hardness and residual stresses in the material.īesides simulations of forming processes on a continuum scale, we carry out simulations of microforming processes (< 1 mm3), using the crystal plasticity theory.An integrated computational materials engineering (ICME)-based workflow was adopted for the study of microstructure and property evolution at the heat-affected zone (HAZ) of gas metal arc-welded DP980 steel. In addition, it is possible to establish the nature of the load acting on tools (mechanical and thermal) and the time dependence of total forming forces.īy means of the DEFORM HT module, we can also simulate heat treatment and thermomechanical treatment processes. The simulations provide predictions of temperature, strain and stress distributions and material flow for each time instant of the forming process. The DEFORM system enables us to simulate static load applications (elastic deformation and creep) and the effects of large deformation in hot and cold forming processes. The development of computer models and subsequent numerical simulations are carried out using DEFORM™, a finite element method-based tool. Some of our simulations are intended for research and development projects and others are performed as part of industry contracts. We carry out simulations of manufacturing processes, involving predominantly various hot and cold forming processes and heat treatment.
