摘要:
To combat thermal-induced problems such as residual stress, deformation, and crack, induction heating is introduced into weld-based additive manufacturing process as a controlled thermal intervention. To date, however, numerical simulation of this induction-assisted weld-based additive manufacturing process is still a tough task; for conducting transient thermoelectromagnetic motion, coupling analysis is computationally prohibitive. In this paper, a simulation strategy is devised to address the problem. The coupling analysis is performed only at a typical time to obtain the representative dist...
