... that the fracturing had something to do with the precipitation of sigma phase. Metallographic examination showed that the multiaxial stresses caused by sigma phase formation and the related embrittlement was the cause for the fracture of the recuperator. A steel of lower chromium content with no or little tendency...

Because most real-world structures and components are typically subjected to more complex multiaxial stress states rather than constant uniaxial load, it is important to be able to predict the creep deformation and rupture behavior under multiaxial stress condition using...

... a stress concentration factor of perhaps 4 to 5. Finally, the multiaxial stress state resulting from the overall and local geometries could have allowed the stress at the origin to approach the uniaxial yield strength, without being relieved by plastic flow. In view of these factors, a local stress level...

... of displacement. The reason for this deviation is the fact that multiaxial stress states do affect the yield behavior of plastics. Compared to uniaxial tensile loading, the yield strength is greater in compressive and less in shear or biaxial tensile loading ( Ref 17 , 18 ). Thus, the third model improves...
