Techniques are reviewed for the calibration of constitutive relationships for the different phases of the weld. It is shown how the calibration is carried out using property ratios, and a knowledge of the constitutive equations of the parent material. The results of CDM analyses, obtained using the two-dimensional solver Damage XX, are reviewed for: a butt-welded pipe at 565°C; and, a welded cylinder-sphere pipe intersection at 590°C. Results are then presented of a three-dimensional CDM solution for a three-degree slice of the welded cylinder-sphere pipe intersection, and shown to be in close agreement with the two-dimensional, Damage XX, solution. Then the paper examines damage growth at a constant temperature of 590°C in a ferritic steel butt-welded pipe subjected to a combined constant internal pressure of 4MPa and a constant global bending moment of 49kNm. The CDM results for a three-dimensional analysis are compared with qualitative experimental results, and good correlation is indicated.
