Procédé de perçage par laser : Comparaison entre des données expérimentales et une simulation 2D basée sur la méthode CNEM

Abstract

This work presents a numerical alternative for the laser drilling simulation problem. Using finite element method is difficult to simulate the hole propagation over time, especially because of moving boundaries due to a fast phase change and high thermal gradients. First, the physical process of the laser drilling and the modeling equations are clarified. Then a comparison between experimental data and simulation outputs regarding the laser peak power is investigated.
