Polyurethane Sealant to Mitigate Crack Effects in Glass-to-Metal Sealed Underwater Connectors
… of the insulation is reduced due to surface cracks formed during manufacturing. In this thesis, we propose and test a sealant to overcome limitations associated with internal cracks. The need for a sealant was identified following a series of experimental tests simulating environmental, …

Simulation des Erstarrungsprozesses und des Inline-Walzens von im Strang gegossenen Stahlknüppeln mit flüssigem Kern
… of steel billets with liquid core on the internal quality of billets, casting and soft reduction experiments were carried out. Moreover, the temperature, stress and strain fields in billets were calculated with the finite Element Software ABAQUS to determine the shell thickness, the solid …

Experimental Damage Diagnosis of a Model Three-Story Spatial Frame
… and demolition. Dynamic property shifts can show internal cracks and minor damage before propagation or failure occurs, but only if a proper indicator is selected. In order to evaluate potential damage indices, a three-story metal frame building was constructed. Using Star Modal software, dynamic …

Multi-Class 3D Segmentation of Progressive Damage in Advanced Composites using Deep Learning
… and segments the different damage modes (e.g., internal cracks) in the 2D tomograms that comprise the 3D tomographic scan. However, these scans contain a large amount of data (≈10 GB/mm3 ) making it traditionally challenging to extract mechanistic insights in a reasonable time frame. Thus, as a …
