    Corrosion Behavior of CLAM in Liquid LiPb Alloy at 480°C (2007)

    Notes: China Low Activation Martensitic steel (CLAM), which is one of the RAFMs (ReducedActivation Ferritic/Martensitic steels) and under development in ASIPP, is considered as theprimary candidate structural material and LiPb eutectic as both tritium breeder and coolant of theblankets in FDS series fusion reactors. The corrosion behavior of CLAM steel exposed to the liquidbreeder LiPb is of significance. Corrosion tests of CLAM in flowing LiPb at 480°C were performedup to about 2000 hrs to analyze the corrosion mechanism of CLAM exposed to liquid LiPb. Thespecimens were observed and analyzed by Scanning Electron Microscopy (SEM) and EnergyDispersive X-ray Spectroscopy (EDX) after 500hrs, 1000hrs and 2000hrs corrosion experimentrespectively. The corrosion is of non-uniform and the weight loss was about 0.23 mg/cm2 after 2000hrs’ exposure, which is smaller for CLAM compared to those of other RAFMs

    A Multi-Level Low Cycle Fatigue Damage Model for Forging Die Material (2006)

    Notes: The forging die material, a high strength steel designated W513 is considered in this paper. A fatigue damage model, based on thermodynamics and continuum damage mechanics, is constructed in which both the previous damage and the loading sequence are considered. The unknown material parameters in the model are identified from low cycle fatigue tests. Damage evolution under multi-level fatigue loading is investigated. The results show that the fatigue life is closely related to the loading sequence. The fatigue life of the materials with low fatigue loadingfirst followed by high fatigue loading is longer than that for the reversed loading sequence

    The stability of spectral schemes for the large eddy simulation of channel flows (1988)
    Chichester : Wiley-Blackwell
    International Journal for Numerical Methods in Fluids 8 (1988), S. 1107-1116

    Notes: In a spectral LES code it is not possible to treat the actual eddy viscosity implicitly. We have therefore examined the effect on stability of adding a constant pseudo-viscosity to the implicit term and subtracting it from the explicit term: stability limits have been derived theoretically and verified computationally for two different treatments of the explicit term. We have also studied the effect of a stochastic temporal variation of the eddy viscosity.
