A method for the probabilistic method assessment of structures containing defects
… by noting that the current safety justification of pressurised water reactor pressure vessels is deterministic. To enable probabilistic structural integrity safety cases of reactor pressure vessels to be carried out, a need for a new analysis of the statistical properties of fracture toughness is …

Ultrasonic nondestructive evaluation and imaging of defects in reinforced cementitious materials
Characterization of defect is one of the important objectives of nondestructive evaluation (NDE) for condition assessment of structures. Among many other NDE techniques, ultrasonic methods play a prominent role in the both quantitative and qualitative assessment of discontinuities in reinforced …

Theoretical and experimental modelling of multiple site damage in plate components.
Fracture and fatigue assessment of structures weakened by multiple site damage (MSD), such as two or more interacting cracks, currently represents a challenging problem. The lifetime prediction of structural components with MSD is still largely based on 2D single crack solutions available in …

Generalized finite element methods for three-dimensional crack growth simulations
… (3-D) crack growth analysis is crucial for the assessment of structures such as aircrafts, rockets, engines and pressure vessels, which are subjected to extreme loading conditions. The analysis of 3-D arbitrary crack growth using the standard Finite Element Method (FEM) encounters several …

Stochastic modeling in computational electromagnetics
… thesis presents methodologies for the efficient assessment of the impact of statistical variability on the performance of electromagnetic structures and systems. The proposed techniques are based on the Sparse Grid Collocation method which is a more efficient alternative than the standard Monte …

Ein Beitrag zur experimentell gestützten Tragsicherheitsbewertung von Massivbrücken
… a technical recommendation for the experimental assessment of structural safety and usability of concrete structures. By now, the influence of pavement or floor layers and of other factors on the load carrying capacity is not known exactly. In this thesis, it has been investigated how road …

Multi-axial real-time hybrid simulation framework for testing nonlinear structure systems with multiple boundary interfaces
… structure into numerical and physical substructures, for a space- and cost-effective testing method. Structural elements that are expected to remain in the linear elastic range are usually modeled numerically, while computationally intractable nonlinear elements are tested physically. The …
