A new hybrid explicit-implicit finite element (FE) numerical method is developed to accelerate the simulation of very large-scale transient thermomechanical processes such as welding and additive manufacturing. The new hybrid approach drastically reduces computational time, and at the same time, yields satisfactory outcome for a large class of transient thermomechanical processes characterized by numerous heating and cooling cycles such as multi-pass welding and additive manufacturing of metallic structures.
