  • Using cryogenics to increase the pressure of deuterium-tritium gas is a conceptually simple process. The source of DT gas is maintained at room temperature and near atmospheric pressure. The pressure intensifier is isolated from the gas source with a valve. During operation the intensifier is cooled with liquid helium and the isolation valve is opened. Accordingly, DT gas condenses out as liquid in the cold intensifier vessel. The isolation valve is subsequently closed and the refrigeration withdrawn. Upon warming the trapped DT liquid changes state and produces high pressure gas. Cryogenic pressure intensifying has several unique advantages over the usemore » of mechanical compressors. One advantage is the complete elimination of oil and lubricant contamination in the process gas. 3 figs.« less
  • Development of robust and cost effective method of joining dissimilar materials can provide a critical pathway to enable widespread use of multi-material design and components in mainstream industrial applications. The use of multi-material components such as Steel-Aluminum, Aluminum-Polymer allows design engineers to optimize material utilization based on service requirements and often lead weight and cost reductions. However producing an effective joint between materials with vastly different thermal, microstructural and deformation response is highly problematic using conventional joining and /or fastening methods. This is especially challenging in cost sensitive high volume markets that largely rely on low–cost joining solutions. Friction Stirmore » Scribe technology was developed to meet the demands of joining materials with drastically different properties and melting regimes. The process enables joining of light metals like Magnesium and Aluminum to high temperature materials like Steels and Titanium. Additionally viable joints between polymer composites and metal can also be made using this method. This paper will present state of the art, progress made and challenges associated with this innovative derivative of Friction Stir welding in reference to joining dissimilar metals and polymer/metal combinations.« less
  • Abstract not provided.
  • This paper summarizes the common design procedure and the design process for offshore concrete structures and describes how stress field theories such as the Modified Compression Field Theory as well as conventional Strut and Tie modeling have been applied in some recent projects. This comprises both sectional analyses, i.e. verification of separate predefined sections and analyses of extracted portions/bodies. The theoretical foundation is briefly presented while main emphasis is put on practical examples and experienced gained.
