Abstract Scope |
This study presents a material model tailored for Integrated Computational Materials Engineering (ICME)-based process simulations. The model integrates plasticity and damage evolution mechanisms, offering a refined approach to simulate material behavior under complex deformation conditions. Central to this work is the use of evolution equations for dislocation densities, enabling precise tracking of the microstructural state throughout processing and capturing critical interrelationships among process parameters, microstructure, and properties. By simulating the growth of dislocation densities and development of void fractions in each step, the model ensures accurate transfer of deformation history across sequential stages. Implemented for laser-assisted hole flanging—a multistep process where shear cutting and laser heating influence component quality and performance—this model enhances the fidelity of process simulations. Ultimately, it advances ICME by providing a reliable framework for microstructure-sensitive material modeling in thermomechanical processing. |
