"The well-distributed volumetric heat source model for numerical simula" by Donghong Ding, Shimin Zhang et al.
Abstract Wire arc additive manufacturing (WAAM) is a promising alternative to laser-powder based additive manufacturing for fabricating large metallic components due to its high productivity and low cost. The high heat input of the arc welding process causes significant thermal stresses resulting in large distortion of the components. Finite element methods are widely used to analysis arc welding and additive manufacturing process, while the commonly used Gaussian or Double ellipsoid volumetric heat source model requires a large number of mesh points suffering from computational expensive and...
