Modelling property changes in graphite irradiated at changing irradiation temperature. 7th South African Conference on Computational and Applied Mechanics (SACAM10), Pretoria, 10-13 January 2010, pp 500-5079780620491721http://hdl.handle.net/10204/49077th South African Conference on Computational and Applied Mechanics (SACAM10), Pretoria, 10-13 January 2010A new method is proposed to predict the irradiation induced property changes in nuclear; graphite, including the effect of a change in irradiation temperature. The currently used method; to account for changes in irradiation temperature, the scaled fluence method, is demonstrated.; The proposed method, which makes use of evolution equations to describe the rate of change; of the property of interest, is described in detail. The property value is obtained by integrating; the evolution equation. A sudden change in irradiation temperature instantaneously affects the; rate of change, but the property value itself remains continuous. Numerical examples are used; to demonstrate the increased accuracy of the proposed method.enGraphiteTemperatureIrradiation temperatureState variable formulationApplied mechanicsNuclear graphiteSACAM 2010Conference PresentationKok, S.
