Numerical Study of the Mechanism of Laser Forming Process
K. Paramasivan, S. Das, S. Marimuthu and D. Misra

This paper presents the mechanism of laser bending process. A finite element (FE) multiphysics modelling for the laser forming process of AISI 304 stainless steel is carried out to understand the deformation behaviour of the plate during the process. The temperature, stress and displacement distributions are captured at every single time interval on two mutually perpendicular cross-sectional planes (X-Z and Y-Z) of the plate for better elucidation of the ongoing process. COMSOL MULTIPHYSICS has been used to simulate the temperature distribution and deformation of sheet metal. The plate deformation during the process has been discussed in detail in the present work.
