Atomistic Structure and Dynamic Evolution of Shock Waves in Laser-material Interaction

By: Xinwei Wang Department of Mechanical Engineering, Iowa State University This work reports on the pioneering molecular dynamics (MD) modeling of shock waves in laser-material processing. For pulsed laser-assisted material processing with an ambient gas, the fast melting, vaporization, and phase explosion of the target is a very complicated process and will form a strong […]
