Abstract
A creep strength analysis and assessment method includes comparing whether a maximum value of a local strain and a membrane strain are less than a corresponding allowable strain, and if less, determining that a component is safe; otherwise, performing the following steps: performing stress linearization on a path to obtain a local primary membrane stress Pand a local primary bending stress P; averaging shear stress components on the path to obtain an average shear stress τ; obtaining a strength limit S, a time-independent minimum stress strength value Sand a temperature- and time-dependent stress strength limit Sfor a given material, a design lifetime and a design temperature; comparing whether P, P+Pand P+P/Kare less than S, KSand S; and comparing whether τis less than 0.6Sand 0.6S, and if less, the component is safe, otherwise, the component is unsafe.
