Abstract: Tjunctions are widely used for fluid mixing in power and process plants. Temperature fluctuations generated by the mixing of hot and cold fluids at a Tjunction can cause high cycle thermal fatigue (HCTF) failure. The ...

Abstract: To investigate the failure behavior of piping systems under severe seismic loads considering beyond design basis event (BDBE), an experimental approach to use pipes made of simulation materials was applied. “Simulation ...

Abstract: Ratcheting is a progressive incremental inelastic deformation or strain which can occur in a component that is subjected to variations of mechanical stress, thermal stress, or both. This study concentrated on the ratcheting ...

Abstract: Temperature fluctuations caused by the mixing of hot and cold streams at tee junctions may lead to high cycle thermal fatigue (HCTF) failure. It is necessary to evaluate the integrity of structures where the HCTF may occur. ...

Abstract: Adoption of doublewall straighttube steam generators (SGs) made of Mod.9Cr1Mo steel is planned for nextgeneration fast breeder reactors (FBRs) in Japan. One of the major concerns with the SG is the structural integrity of ...

Abstract: Ratcheting, collapse, and fatigue are the probable failure modes which can occur under alternate dynamic loading like seismic loading. The objective of this study is to propose a failure mode map for rectangular beams by ...
