Application of Abaqus to analysis of the temperature field in elements heated by moving heat sources

Numerical analysis of thermal phenomena occurring during laser beam heating is presented in this paper. Numerical models of surface and volumetric heat sources were presented and the influence of different laser beam heat source power distribution on temperature field was analyzed. Temperature field was obtained by a numerical solution the transient heat transfer equation with activity of inner heat sources using finite element method. Temperature distribution analysis in welded joint was performed in the ABAQUS/Standard solver. The DFLUX subroutine was used for implementation of the movable welding heat source model. Temperature-depended thermophysical properties for steel were assumed in computer simulations. Temperature distribution in laser beam surface heated and butt welded plates was numerically estimated.
