Abstract

We have succeeded for the first time to simulate dynamic phase transition from metal to vapor. This success is due to the CIP (Cubic-Interporated Pseudoparticle/Propagation) method that can treat solid, liquid and gas together and can trace a sharp interface with almost one grid. We report here the application to laser-induced evaporation and welding process. In the former case, aluminum is evaporated well after the laser beam ended and evaporation occurs with a large angle to the target normal leading to large debris. In the latter case, a deep penetration welding of SUS304 by YAG laser has been successfully replicated the experiments and the simulation clarifies the formation mechanism of keyhole.
