2D thermal model for laser heating processes: a finite element approach
Authors: Diego Alejandro Montoya Zapata Juan M. Rodríguez Oscar Ruiz
Date: 28.10.2021
Abstract
For laser-based additive manufacturing, the process parameters are central for the quality of the produced pieces. This manuscript presents a 2.5D Finite Element simulation of the laser-induced metal deposition, which produces the history of temperature in a cross section of the metallic substrate, taking into consideration the laser trajectory normal to the cross section. Particular focus is set on the effect of the geometry of the power density of the laser on the process upon the thermal response of the substrate. Three laser intensity distributions are considered: Gaussian, uniform circular and uniform squared.
