Abstract

  To analyze residual stress of sand mold iron castings, a computer simulation method has been developed. The simulation has been done by using a commercial finite element code (ABAQUS ver. 4.8). Measured temperature distribution of a casting has been used as a load condition in the simulation. The simulation results, i. e. residual stress distribution under various conditions of casting's shape or cooling condition, have been nearly agreed with experimental results. Therefore, this simulation method seems useful for designing of castings.
