‘damage‘ in the material. Conventional and nuclear power generating plant are generally designed on the basis of continuum failure, with assessment routes providing an indication of the effects of flaws on component performance. Another example where an understanding of creep failure is important is

Physical Interpretation Of Creep and Strain Recovery of a Glass Ceramic Near Glass Transition Tempertion of defects-ii) .max : characteristic time-iii) b: parameter characterizing the effectiveness of correlation effects (0<b<l). There is a good agreement between experimental and calculated creep curves. In addition, the evolution of A, .max and b with the microstructure change of glass could be interpreted in a consistent way.

The Double Torsion Test Applied to Fine Grained Freshwater Columnar Ice, and Sea Ice jump length was found to be correlated to the drop in stress intensity factor, but not to load rate. The arrest stress intensity factor appears to be the creep free fracture toughness, and was the same for both types of ice.

Ice and Steel - A Comparison of Creep and Failureparable and, in many instances, complementary. Grain size has been shown to play a major role in determining the overall creep response and damage accumulation, and thereby makes the model useful in understanding the response of heat affected zones in weldments in steels.

The Brittle-To-Ductile Transition in Siliconependence of the transition temperature, T., is controlled by dislocation velocity. Etch pit observations show that dislocation generation from the crack tip begins at K just below K., from a small number of sources around the crack tip. The dynamics of plastic relaxation has been simulated on a mod

Stress Redistribution Effects on Creep Crack Growth(t), to steady state values described by the parameter C* For creep ductile materials, the transitional phase before attainment of the steady state is usually neglected and crack initiation and subsequent creep crack growth rates can be determined from calculations of C*. However, for creep brittle

Modelling of Creep Crack Growthpreserved at a crack tip it is shown that crack growth rate can be correlated by the stress intensity factor K and when a creep stress distribution is attained by the creep fracture parameter C*. However since creep strains of about the elastic strains only are required for stress redistribution, it

Modelling Creep-Crack Growth Processes in Ceramic Materialsral, have a fairly complex influence on the stresses and displacements occurring in the undamaged material. However, there are two limiting types of behaviour that result in significant simplifications to the analysis. If the interaction between the damaged and undamaged regions is negligible, then
