説明

The effect of solid-state phase transformation at low temperatures on residual stresses in butt welded ferritic thin steel plates has been examined employing a finite element (FE) code. An algorithm considering the solid-state phase transformation has been developed and implemented in a thermo-elastic-plastic analysis of an in-house FE code developed at JWRI Osaka. A number of analyses have been conducted to examine the effect of Martensite start (Ms) temperature on residual stresses. It has been shown that solid-state phase transformation at low temperatures has a profound effect on residual stress state in welded thin steel plates.
