Abstract Scope |
Process modeling of metal additive manufacturing is a multiscale multiphysics simulation, and it needs a massive CPU time if physical details are involved. According to the simulation goal, we can apply some meaningful assumptions to handle the CPU usage. One of the subjects is laser heat input physics and the related physical consequences. This research has developed a pseudo-function for the laser heat input with melt-pool dynamics and metal evaporation physics analytically, meaning as a correction term to the laser heat input function. With this pseudo-function, CPU time could be dramatically reduced. The melt-pool/HAZ depth, residual stress, total deformation, and local cooling rates could be simulated without directly stimulating the melt-pool dynamics and metal evaporation effects. This function will be efficient for design proposes and accelerating technical innovations in metal additive manufacturing with the powder bed fusion method. |
