Knowledge-based system for on-line stress evaluation in thick walled vessels in thermal power plants

Creating of knowledge by simulation using dedicated software for the calculation of the transient temperature field and the corresponding stress field on a component of complicated geometry and the use of such knowledge for on-line estimation of the component's strength margin during plant operation is proposed. A tentative concept of such a system is described and some results of the preliminary investigation obtained by a simplified model are presented.
