Effect of thermal modeling assumptions on prediction accuracy and computational efficiency in laser-arc hybrid welding simulation

Laser-arc hybrid welding (LAHW) imposes steep, localized thermal gradients demanding computationally expensive thermo-elastic-plastic (TEP) finite element analysis. To quantify the trade-off between physical fidelity and computational efficiency, three TEP models of LAHW on a 300...
