Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... 詳細を見る

Joule heating is simulated in COMSOL Multiphysics® software for the electro-thermal micro actuator. The aim is to choose the optimal design parameters to get the largest possible in-plane displacement. The comparison between the different possible configurations will reveal the optimal ... 詳細を見る

Analysis of concrete structures is usually carried out by destructive methods. The internal volume flaws directly influence concrete properties. Such inclusions are empty or even resulting from the manufacturing process or degradation by percolation leaching dissolution and chemical ... 詳細を見る

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, ... 詳細を見る

CV boots or gaiters are rubber like material used to cover & protect moveable or articulating components such as CV joints of a vehicle. These are primarily used to protect the articulating joint, by preventing the components from being exposed to the surrounding environment, the ... 詳細を見る

Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by ... 詳細を見る

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. ... 詳細を見る

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 ... 詳細を見る

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded ... 詳細を見る

This study is to investigate the velocity pattern and the velocity magnitude of the cuttings that is being processed in the process mill as a result of the rotating hammers. The process mill consists of a horizontal cylindrical shell equipped with renewable liners and rotating hammers ... 詳細を見る
