By incorporating the film slip-dissolution/oxidation model and the elastic-plastic finite element method (EPFEM), the effect of the over load on stress corrosion cracking (SCC) growth rate of stainless steel in high temperature water is discussed in this paper. Results sho w that SCC growth rate of a 20% cold worked 316L stainless steel in high temperature water decrease in the overload affected zone ahead of the growing crack tip. Therefore, a reasonable overload could availably reduce the SCC growth rat...

Effect of Overload on SCC Growth in Stainless Steels in High Temperature Water

Abstract: When multi-faults state occurred in a plant rotating machine, because the relationship between fault types and vibration signals measured for the diagnosis are much more complex than the case of single fault, moreover, the condition diagnosis information from vibration signals is ambiguous, especially at early stage, the diagnosis for the multi-faults is more difficult. In order to resolve the problem, this paper proposes a new precise diagnosis method for rotating machinery using support ve...
