Abstract: Creep rupture strength of creep strength enhanced ferritic steels is often overestimated, and its evaluated value has been reduced repeatedly. In this paper, the cause of the overestimation is discussed, and the creep ...

Abstract: Conventional timetemperatureparameter (TTP) methods often overestimate longterm rupture life of creep strength enhanced ferritic steels. Decrease in activation energy Q for rupture life in longterm creep is the cause of ...

Abstract: nonparametric stochastic model is developed and tested for the simulation of tropical cyclone tracks. Tropical cyclone tracks demonstrate continuity and memory over many time and space steps. Clusters of tracks can be ...
