Implementationof finite element analysis and proof of its power as a design to ol to an industry unfamiliar with this type of technology will be demonstrated through the use of MSC/NASTRAN and MSC/ARIES to develop a comprehensive guitar neck system. This system will provide a better playing, better sounding instrument by accounting for the following: −bending and twisting of the neck due to str...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...

Past research has confirmed the existence of surface nanobubbles on various hydrophobic substrates (static contact angle >90°) when imaged in air-equilibrated water. Additionally, the use of solvent exchange techniques (based on the difference in saturation levels of air in various solvents) also introduced surface nanobubbles on hydrophilic substrates (static contact angle <90°). In this work,...
