| Abstract: | Thermo-mechanical finite element analysis has been performed to assess the
residual stress in the butt-weld joints of 2.25Cr1Mo low-alloy-ferritic steel
plates and ASTM36 steel plates utilizing the commercial software package ANSYS,
employing 2D plane stress models. Temperature dependant properties of the
materials are specified. The radial heat flux distribution is considered on the
top surface of the weldment. Convective and radiative heat losses are taken
into account through boundary conditions for the outward flux. The present 2D
plane stress analysis results are found to be in good agreement with existing
3D finite element analysis and experimental results. 2D welding simulations are
not only reducing the complexity of the problem, but also providing the nature
of residual stress in weldments with reasonable accuracy. |
