摘要：
A hybrid method combining the accelerated explicit and the implicit FEM was developed for simulation of welding thermal stress. Furthermore, to reduce the computing time and keep the simulation accuracy, the hybrid modelling using solid elements around the welded zone and shell elements in the zone away from the welded zone is recommended. The applications of hybrid method and hybrid modelling to the simulation of welding thermal conduction, thermal stress and strain showed a good efficiency.
