A mathematical model of induction-assisted 3D printing is presented, providing a tool for design of specified tracks printed on suitable substrates. The model consists of the non-stationary temperature field produced by laser beam and field of deform

Purpose A model of hybrid fillet welding is built and solved. No additional material (welding rod, etc.) is used. Heating of the welded parts is realized by laser beam with induction preheating and/or postheating. The purpose of these operations is t

Novel approach to modeling of 3D coupled electroheat problems with time-varying geometries is presented. Instead of time-expensive remeshing of the whole system in every time step it is used the initial mesh that takes into account the expected geome
