Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, thus, narrow bandwidth. Therefore, it requires optimal mechanical design of the cavities to minimize the ...

Solders are typically used to join similar or dissimilar metals, referred to as substrates. In some cases solders are also used to join completely different classes of materials. For example, a joint between copper busbar and silicon solar cell represents a set of dissimilar substrates. In the formation of a solder-substrate couple, the system must have been subjected to at least a single ...

Sensors have diverse applications ranging from the medical field to space exploration. They convert physical parameters such as temperature, pressure, humidity etc. into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of pressure sensors. Improvement in the sensitivity is the major factor to be considered while designing pressure ...

The increasing demand for improved metallurgical products strongly motivates the optimization of manufacturing processes and design of γ-TiAl products. Among the large variety of available forming processes, cold closed-die forging is particularly suitable for producing net shape bulk products having good surface finish with better mechanical properties. Pressing punches of suitable profile ...

This paper deal of the forming process applied to the thermoplastic composites. A new thermoforming process that uses rubber particles collection as flexible mould was presented and numerically modeled. A characterization of the rubber in particles form was previously performed to value the material parameters in the user-defined hyperelastic constitutive laws employed in the FEM (Finite Element ...

Musculoskeletal mineralised tissues (MMTs), like bone or tendon, are a prime example of naturally occuring, hierarchically structured material. They display a great variety in mechanical function but are all based on essentially the same building block: the mineralised collagen fibril (100 nanometer in diameter). This building block is arranged in various spatial structures across many length ...

Studies by Nishaat (2009) showed that Terzaghi\'s bearing capacity model didn\'t adequately predict the bearing capacity failure in Philippi Dune sands. Nishaat carried out her investigation using a physical model that was built in a geotechnical laboratory. The failure surfaces she observed in the sands did not resemble those predicted by Terzaghi and Meyerhof\'s models. However the use of a ...

The actuator comprises of a temperature sensitive composite deflecting beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes an expansion in the composite beam thereby causing it to deflect. The deflecting beam impinges on the piezoelectric crystal and generating voltage. Response curves for the deflection versus temperature for temperature ranges ...

Two bimorph array facing opposite to each other are designed and attached with metal micro plates. The micro solar cell (or) film can be placed on the top of each plate for storing the energy. With respect to the direction of sun light, one bimorph array receives more energy in the form of heat than the other and deflects accordingly. The deflection of the bimorph array depends on the material ...

Utilization of bioreactors to regenerate tissues outside the body has been intensely investigated in functional tissue engineering. Various studies have been performed using computational fluid dynamics (CFD) to understand fluid flow within bioreactors while assuming porous scaffold as a rigid structure. However, the physical and mechanical properties of most tissue engineering scaffolds suggest ...
