Abstract | ||||
ABSTRACT A two-dimensional cylindrical axisymetrical model for laser-metal interaction is presented in this paper by taking into account the reflection of the laser beam at the surface of the target, the initial and boundary condition, using the continuous and pulsed Gaussian Nd:YAG laser beam. The problem was solved using finite difference method and using Newton Raphson method to calculate the position of the interface, the metals were studied are pure aluminum, magnesium and titanium. The model allows both for heat conduction and melting inside the target. The computational results are temperature fields in both solid and liquid were obtained which provide useful information to practical laser treatment processing. | ||||
