A thermoelastic model was used to predict dislocation generation during the edge-defined film-fed growth of polygonal shells. An 8-node degenerate shell element with a degree of freedom, and micropolar elasticity theory were used to calculate the stresses in the polygonal shell during an arbitrary temperature decrease. On the basis of the calculated stresses in the polygonal shell, the evolution of dislocations and creep strain rates were estimated by using the Alexander-Haasen constitutive law.
