| Popis: | Service life extension of PWR vessels is an important issue for a number of nuclear operators. This aim is partially subjected to improvement of safety margins. These margins may be enhanced by acceptance of a limited amount of crack growth, starting from an initial flaw. It is therefore necessary to predict not only the crack initiation but also the crack arrest. It is also of great interest to compare dynamic and static analysis and to know if quasi-static prediction is a conservative way or not. Analytical investigations for actual structures are rather complex to carry on. An academic problem theoretical analysis is therefore useful, in a first step, to understand the different features of dynamic crack propagation and arrest. Moreover, numerical investigations may usefully complete the analysis. |
