  • Taking into account temperature-dependent thermal conduction and heat capacity,a three-dimensional transient finite element model was established.A sequentially analysis of coupled thermal-stress was employed.Some conclusions related to the simulation results are made:maximum thermal stress lessens with sintering going on owing to effect of sintered region;the region ahead of sintering has greater stress distribution than behind.
