Grahic Jump Location
Finite element discretization used for analyses of the welding of membrane to tube. The coordinate system is defined as follows: 1—radial in the tube, transverse in the membrane; 2—hoop in the tube, normal in the membrane; 3—axial in both the tube and the membrane.
Grahic Jump Location
(a) Hoop and (b) axial stress distribution [MPa] in the tube and membrane assembly after the welding operation.
Grahic Jump Location
Finite element discretization used for analyses of a normal operating cycle, showing the temperature distribution [°C] on the fireside surface.
Grahic Jump Location
Variation in (a) hoop and (b) axial stress at the fireside crown of the tube for the three clad materials during a normal operating cycle.
Grahic Jump Location
Variation in (a) coefficient of thermal expansion and (b) yield stress with temperature.
