Abstract

The ability to incorporate real, temporally variant intensity distributions is key to improving the accuracy of Finite Element (FE) models of laser processes. The work presented in this paper uses Laser Forming as a process example. Laser forming (LF) offers the industrial promise of controlled shaping of metallic and non-metallic components for prototyping, correction of design shape or distortion and precision adjustment applications. In order to fulfill this promise in a manufacturing environment the process must have a high degree of controllability, which can be achieved through a better understanding of its underlying mechanisms. FE modeling can be used to gain this understanding.
