Laser Assisted Machining (LAM): Modeling and Simulation in Abaqus/CAE

 310.0

In this tutorial, a comprehensive discussion on modeling and simulation of laser assisted machining is presented. It includes building FEM-based models of machining, laser heating, and laser-assisted machining models in Abaqus/CAE. The finite element method (FEM) simulation is based on the coupled thermo-mechanical behavior. The package walks learners through building models that simulate the impact of laser heating on the workpiece. Detailed lessons cover constructing basic machining and laser heating models, setting boundary conditions like cutting speed and laser power, and writing subroutines such as DFLUX and VDFLUX to simulate laser heat sources. Additionally, learners will perform analyses to study temperature distribution, and stress-strain behavior. Through parametric analysis and comprehensive result evaluation, learners will gain a deep understanding of temperature distribution, stress behavior, and how laser heating can improve the machining process.

DFLUX Subroutine (VDFLUX Subroutine) in ABAQUS

DFLUX subroutine (VDFLUX Subroutine) is used for thermal loading in various body flux and surface flux states in heat transfer and temperature displacement solvers when flux load is a function of time, place, or other parameters. In this package, you will learn “when do you need to use this subroutine?”, “how to use the DFLUX subroutine”, “what is the difference between DFLUX & VDFLUX?”, “how to convert DFLUX to VDFLUX and vice versa?”, and “How to use it in an example?”. Three workshops are presented so you can learn all these stuff in action: Simulation of welding between two plate with DFLUX subroutine, Simulation of Arc welding between two tube with DFLUX, and Simulation of different types of functional heat flux(Body-surface-Element) in plate with Johnson-cook plasticity with VDFLUX subroutine(Thermomechanical Analysis).
