Laser-assisted Advanced Manufacturing

 

In laser material processing and laser-assisted advanced manufacturing, the target under pulsed laser irradiation could experience intense phase explosion, extremely high stress wave generation/propagation, and solidification/recrystallization. Our atomistic and atomistic-macroscale computations are designed to investigate these phenomena and study the relation between them and laser irradiation conditions and material properties.
