Numerical Simulation of Cylindrical Hollow Steel Specimen in Quenching

Abstract:

using finite element method to study the stress variation of cylindrical specimen during the cooling process of quenching, through the establishment of the computer models of mechanical property and thermal property, and using computer to perform the numerical simulation of temperature environment and structure in the process of quenching, simplify the operation process on one hand, and facilitate the analyses of complicated nonlinear problems on the other hand. The outcome according to the stress variation of the outside surface of cylinder indicates that during the process of quenching, the cooling speed of the inner surface of cylinder is much slower than that of the outer surface, leading to the reverse between the center stress and the outer surface stress of hollow cylinder, which finally turns into internal stress distribution of structural stress type.
