Calculs thermomécaniques pour la conception de structures réfractorisées
Keywords:
refractorised structures, equivalent two-layered shell element, inverse identification, thermomechanics, smeared crack model, expansion jointsAbstract
Degradations in refractorised structures can appear during using. To limit these degradations in improving the design, it is necessary to have adapted finite element computing tools. For simple structures, like steel ladles, a 3D computing can be performed. On the other hand, for more complex structures, like coal fired power plants, the use of a simplified element is essential. It is here a two-layered shell element that has an equivalent bahaviour to the set of metallic casing and refractory lining.
