| Summary: | The finite element method (FEM) is employed to investigate the residual stress state and
the variation of internal stresses in the St5O cylinder bar quenched from 600 to O°C.
Thermal analysis is first performed to obtain the cooling curves for the core and surface
of the bar, this is followed by a full structural analysis. The results obtained from the
computer simulation are compared with those experimentally determined values that are
available in the literature and there appears to be a good measure of agreement. The
study found that at the initial stages of the quenching process, the residual stresses were
tensile at the surface and compressive in the core, however, towards the end of the
quenching process, the tensile residual stresses switched to the core and compressive
residual stresses at the surface. |
