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

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

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
