| Thin-walled structures are important elements of many important industrial areas such an aerospace, shipbuilding, pipelines and others. On the other way sometimes is necessary predict fatigue damage from thin and small specimens for relatively big structural components. Therefore, accurate transfer of the experimental results obtained from thin and small specimen to big structural components and vice versa is general goal of the project. Based on finite elements numerical calculations of thin-walled structures will be developed procedure describing crack type damage in thin-walled structures. Experimental verification will be made using Eurofer 97 and feritic oxide dispersion strengthened (ODS) steels which is perspective structural material of DEMO fusion reactor. Generally, the predictive power of the approaches developed within this project will help towards a better understanding of thin-walled structure failure and more reliable prediction of their residual life time. |
